If that is the case, that cellphone usage is *not* distracting, then,
instantly, that would *solve* the paradox.
 
But, then, how do we reconcile that observation with the fact that
(unnamed) "studies show" that cellphone use is "as distracting as
driving drunkly"?
 
The *new* paradox looms - which is - if cellphone use isn't distracting,
then why do "studies show" that it *is* distracting (as drunk driving)?
 
Nothing makes sense in all these arguments.
There is very little intelligent discussion.
 
So, maybe the solution to the paradox is, as you said, "it really
doesn't matter" whether someone is using the phone while driving,
or not, with respect to accident rates in the USA???
 
But that flies against "common wisdom".

Most people lie on accident reports to avoid potential complications
with insurance payments. For example, few will admit that it was
their fault when the traffic policeman is standing there just waiting
for a confession and to deliver an expensive ticket.
 
Anecdote time. While going to medical skool, a doctor friend worked
in the coroners office of a large city. Like all large cities, the
coroners office had a steady stream of deadbeats, bums, winos, and
homeless that arrived without the benefit of medical attention and
records. Not wanting to spend the money on an autopsy and a medical
examiner, they quietly guessed at the cause of death with fairly good
accuracy. However, after a few embarrassing mistakes, that was deemed
unacceptable. Causes unknown were also not a viable option. So, they
inscribed "heart failure" on all such cases, which was certainly true,
but not necessarily the cause of death. That actually worked well for
a few years, until someone ran statistics on what appeared to be a
heart disease epidemic centered in this large city. The city now
requires either an attending physician report or a mandatory autopsy.
 
While I'm not in a position to prove or demonstrate this, I think
you'll find that such "accident" reports are highly opinionated, are
skewed in the direction of smallest settlements, and are rarely
corrected.
 
>The numbers are high enough, and consistent enough, to make the error
>only a very small percentage.
 
Right. Big numbers are more accurate.
 
The theory is that given a sufficiently large number of independent
studies, the errors will be equally distributed on both sides of a
desired result, and therefore cancel. That has worked well for global
warming predictions. Unfortunately, the studies have to be
independent to qualify and does not work at reducing the distribution
in a single study.
 
>You won't get *better* data that the census bureau data on accidents in
>the USA by state - and none are showing what we'd expect.
 
OMG! Do you really trust the government to do anything correctly? I
wish I had your confidence and less personal experience. I'll spare
you another anecdote illustrating the problem at the city level.
 
>Hence the paradox.
>Where are the accidents?
 
Ok, think about it. You've just crashed your car into an immovable
object while texting. You're still conscious and on an adrenalin
high. The police are on their way and the last thing you need is for
them to find your smartphone on the floor of the vehicle. So, you
make a phone call to your wife telling her you'll be late for dinner
and by the way, you've decided to buy her a new car. The police walk
up, ask you a few questions, and notice you talking on the cell phone.
If you're cooperative, nothing happens. If you're a total jerk, the
mention the cell phone in their report, and you get nailed for
possibly talking/texting while driving. You're screwed if they
confiscate the phone for forensic analysis or request a call record
from you provider.
 
In short, the statisics are where they want them. If there's a
political or financial benefit to showing huge numbers of talk/text
driving accidents, they will magically appear. If they thing that
nobody really cares about the numbers, you will have a difficult time
finding them. If the numbers accumulate some academic interest, you
will see the same wrong information repeated endlessly in statistical
surveys and college dissertations. Everyone lies, but that's ok
because nobody listens. Incidentally, 87.3% of all statistics are
fabricated for the occasion.

It's true, playing music can be pretty distracting. It isn't normally,
but sometimes it can be.

Well, around here, driving drunkly was common and normal behaviour for
a large segment of the population thirty years ago, and now it isn't.
Perhaps as a hazard it has disappeared and been replaced with texting
while driving instead.

This is true, because there is very little actual data. So an intelligent

Police and fire do not "type" on their mobile terminals. Most are set
to not allow input while moving. They also do not talk all day on the
radio. Just listen on a scanner and see how often someone actually
talks while moving. It's rare and maybe once per WEEK per officer at
most. Only in hot pursuit will they talk while moving. If there are
two officers in the car, the passenger will do the talking.
 
There are also other users of mobile data terminals that are exempted
by the Calif Vehicle Code. While the law was written to prevent
people from watching TV while driving, it has been expanded to data
terminals, GPS, computahs, etc. Section 27602:
<https://www.dmv.ca.gov/portal/dmv/?1dmy&urile=wcm:path:/dmv_content_en/dmv/pubs/vctop/vc/d12/c5/a5/27602>
 
Note that ham radio operators have been exempt. Part of the reason is
that there was no evidence of any significant accidents or fatalities
to hams resulting from talking while moving when the ordinance was
inscribed. There are about 2,000 ham operators in the county. I
think I've met about 1/3 of them. In the last 40 years, I don't know
of any that have died or been injured while driving, much less while
talking on the radio.
 
So, what's the difference between texting, talking, and ham radio
operation? Ham radio is a simplex operation. You can only talk and
listen, one at a time, and not simultaneously, such as on the
telephone. We seem to be able to handle either the input or output
channel quite easily, but not simultaneously. I've done some crude
testing to see if that's true. When I use a PTT (push to talk
microphone) to make a phone call while moving, there's no problem
because my caller and I are operating simplex. The same operation
done with a handset, in full duplex mode, it highly distracting and
sometimes confusing.
 
If you want innovation in this area, consider adding a typical mobile
radio microphone to a cell phone, add a loudspeaker, set it up for
simplex, and maybe the mythical accident rate will fall. If not, I
can probably arrange the statistics to demonstrate that it will.
 
For texting, I had a recent bad experience. I was the passenger in a
car where the driver was getting "notifications" continuously roughly
twice per minute. The phone would make an obnoxious noise when they
arrived. He just couldn't resist the temptation to look at his phone
and see what had just arrived. I mentioned it to him, and was
ignored. There was no interactive texting or chat session, but plenty
of approximately 3 second distractions. That's enough for an
accident. Fortunately, there were none, although I was tempted to
kiss the ground as I exited the vehicle.
 
>would expect properly done research would show it's in a whole
>different class of hazards from talking on a phone. But that's just
>an expectation.
 
Yep. You got it. The smartphone has an accelerometer and can easily
tell when it's moving. Buffer incoming texts and block the keyboard
while the phone is moving. End of problem (until it's hacked).
 
Apps are already available but it really should be built into the
phone firmware:

Speaking of the UK, they did a study of the influence of speed cameras
(they have a LOT of them) on accidents and it showed that where there
were cameras that statistically the accidents INCREASED. They
attempted to bury the report. It was eventually released but
uniformly ignored by those in power. Further proof, as if more was
needed, that speed cameras are for revenue, not safety.

Around here, it is routine to see two officers in the car. When they
are not on their way to a call, one officer is driving while the second
officer is typing every license plate he sees into the terminal and
running plates as fast as he can in hopes of finding a car with
outstanding warrants. There is a very distinct division of tasks.

Think again. The Fermi Paradox is better stated as:
"Absence of evidence is not evidence of absence".
Much of this has its basis in theology where wrestling over the
existence of God is an international sport. A more simplistic version
is that you can't prove anything with nothing as evidence.
 
The corollary also doesn't work where:
"Quantity of evidence is not evidence of quantity".
In other words, just because you have a large pile of numbers, doesn't
mean you can prove a large number of things.
 
The problem is that the "Fermi Paradox" is the logic sucks.
 
"The great Enrico Fermi proposed the following paradox. Given
the size of the universe and evidence of intelligent life on
Earth making it non-zero probability for intelligent life
elsewhere, how come have we not been visited by aliens? Where
is everybody?, he asked."
 
No matter how minute the probability of such life, the size
should bring the probability to 1. (In fact we should have
been visited a high number of times: see the Kolmogorov and
Borel zero-one laws.)
 
So, what's missing? Well, it's time or rather how many solar
revolutions a civilization can exist without destroying itself or
having some cosmic catastrophe do it for them. The details are worked
out in the Drake Equation:
<https://en.wikipedia.org/wiki/Drake_equation>
which computes the probability of two civilizations coming into
contact. If you happen to be a pessimist, and use pessimistic
probabilities, the probability might as well be zero. Inflating the
statistical population to astronomical proportions does nothing to
change the probabilities and certainly will not result in a 100%
chance of an alien encounter.

>Where are all the accidents?
 
How about under reporting?
 
How could cell phone-generated accidents get into the system as such?
 
Guy I used to windsurf with bought the farm a couple of years ago when a
guy in an F-150 drove into him from the back at highway speed (i.e.
50-60 mph).
 
He was riding on a wide shoulder, bright clear day, no intersections.
 
I have a hard time imagining that the guy who killed him told the
investigating officer "Yeah, I was just so into this (cell phone
conversation/text message/email) that I drifted on to the shoulder and
drove right into the victim."
 
Same with the buy who almost got me on the Atlantic City Expressway a
couple years ago: I'm running the right lane, guy in the left lane just
starts drifting into me and I can see him holding something in one hand
and poking his finger at it with the other hand (steering with his
knees?).... I took the shoulder and avoided contact - but if there had
been an accident I would not have expected the other driver to 'fess up.
 
Same with the guy in a pickup truck that almost nailed me on my bike
several years ago. I was riding on a very large cross-hatched (no
cars) area. I saw him coming - intent on *something* between his
knees... I zigged, he didn't zag and then he drove right through the
space I was occupying... never looked up. If I had woken up dead that
day, I am pretty sure he would have some other explanation than "I was
absorbed in my cell phone".
 
And then there is the Canadian study that equated driving while talking
on a cell phone with some level of alcohol intoxication....

Sounds like New Yuck City. You must live in a technically

Enrico Fermi said that? Because it's not true. Until humans on earth
invented radio, less than 200 years ago, there were no signals from us.
 
And none of our radio waves have reached places 200 light years away or
more even now.
 
Plus there are animals living in the woods and rivers and oceans and on
mountains and underground that people who never go to those places never
see and only know about because others have told them. If others didn't
tell them, they wouldn't know. If the animals there are sending out
signals, they are short distance signals and they don't reach me.

You've missed the point. All those things you raise may well be true
but they were just as true before there were cell phones. The mix of
truth and lies in accident reports goes on but one key thing continues
and that is that virtually ALL significant accidents, certainly those
society might want to concern itself with, are REPORTED and go into
the statistics of HOW MANY accidents. Yeah, the listed causes might
be lies or honest mistakes but the NUMBERS are reported consistently
year after year after year. And its the NUMBERS of accidents ceg is
talking about as the data set, not the CAUSE that's listed. So we
know that the NUMBER of accidents, rate actually, the normalized
number, has steadily been going down down down.
 
Yet there are people claiming that a NEW and HORRIBLY DANGEROUS CAUSE
of accidents has been unleashed into the driving world, the Cell
Phone. We can't argue with the fact that over the past two decades
MILIIONS AND MILLLIONS of cell phones wound up in the hands of and
used by drivers, that's just a fact. But if all those cell phones are
REALLY this horribly DANGERIOUS ACCIDENT CAUSING instrument, WHERE ARE
THE ACCIDENTS????

The thing is that probabilty on a yes or no question is only valuable
for betting parlors and insurance brokers, which are really the same
thing. One may thing the probability is very high, because there are
so many places life could be, but if there is no life beyond the earth,
it doesn't matter what the probability WAS.
 
It is partly tied up with theology, iiuc, in that some believers in God
want to believe that this earth is his only creation. I don't know why
they would think that either.
 
Another problem, IMO, is that scientists, as reported by the news, seem
to think life could only be water based, and seem to discount places
without water. . I know water has advantages, but it's not the only
possibility.
 
Still, I wouldn't be surprised if there were no life anywhere else.
There are cerrtainly lots of places beyond earth with no life, so why
not more.
 
OTOH, if there is life, I see no special reason they would have a radio
transmitter. Until I got a cell phone, I didn't have one.

No non-sequitur. The statistics ARE reliable as a year to year
measure. That an individual report may have errors is unquestionably
true. But the only number of significance is simply the NUMBER of
REPROTED accidents, not the accuracy of the little details of the
reports. If Officer Odie is dyslexic and instead of Hwy 52 MP 429 he
puts Hwy 25 MP 249 the report will be off by perhaps hundreds of miles
but that ACCIDENT occurred and it is included as part of the Total
number of accidents that go into the rate. Unless you want to make an
argument that there is some systemic problem where the same accidents
are getting reported multiple times for almost every jurisdiction in a
state or that the dog is eating the reports before they are filed I
don't see any reason to challenge the basic accident rates as accurate
enough for this discussion.

I've elaborated on that very question earlier in this thread. The
short version is that most of the 'studies' are crap designed to prove
cell phones are dangerous thru a variety of nonsensical study
protocols. You want to prove pianos are dangerous? Do a study where
one person puts their head under the upraised and held in place by the
stick "hood" of the piano then simulate a magnitude 6 earthquake.
You'll find pianos to be quite dangerous.

No, there is a LOT of data. And contrary to the theorizing of the
alarmists, there is no REAL WORLD evidence that the literal explosion
of cell phone use has caused even a blip in accident rates. A few
anecdotes of 'I saw Santa on his cell phone and he drove his sleigh
right into the side of the chimney" don't prove that cell phones are
some special case of distraction that should be outlawed while we
still allow the carrying of chatty passengers, the eating of food, the
application of lipstick, and the fiddling with CDs and MP3 players.

Thirty people took the test. The show aired 9:30 CDT on August 16.

So using a cell phone should be much more dangerous AND result in a
SIGNIFICANT increase in accidents over the past 20 years as the use of
cell phones has exploded. Yet there isn't the slightest evidence of
that in the accident data.

From my standpoint, there are essentially no new accidents. One
distraction has replaced another. It's even possible that people who
in the past would have fallen asleep did not today because they were
on their cell phone and that engagement kept them awake. But no one
knows.... How do you quantify and categorize accidents that didn't
happen?

And if everyone had DRL's accidents would be reduced another 30%. And
if everyone had ABS another 25%. And if everyone had drivers Ed,
another 10%. And if tire laws were more stringent we could reduce
accidents another 15% and if every state had mandatory inspections
another 10%. By the time we get done with all our "improvements" we
won't need to manufacture new cars, the accident rate will be negative
and new cars will be spontaneously popping out of the road.
