      You know, studies have actually been mixed in regards to this. Mythbusters even attempted to replicate a study that was performed; however, I was a bit skeptical of their approach since it relied on asking questions during the cell phone section that would require some degree of actual thinking and/or decision making. Most conversations I have had on a cell phone, even those not done while driving, have hardly required much thought. The calls I typically make are fairly normal conversation with either my mother or one of my friends.

      I believe that my driving is no worse with the cell phone since I drive one handed anyway, and I believe that for most phone conversations the drivers are no worse then those who are smoking, playing with the radio, or eating while they drive. In fact, I would not be surprised to find people are as poor at driving with a hands-free set for their phone as they are holding the phone. In reality, I think the worse distractions do not come from the phone, but from people who may be in the car. I cannot count the number of times I see the person driving take their eyes of the road in front of them to look at the wife, girlfriend, son/daughter, or other individual riding in the car with them. Maybe it is just me, but this is far more dangerous then having a conversation and keeping your eyes on the road.

      My guess is that it's the brain, not the hands, that makes you more likely to have an accident while talking on the phone. When I'm on the phone, especially during a long call, I tend to notice a change in my spatial awareness: I become less aware of the space around me, and more aware of the space around the person I'm talking to, particularly if they're in a place with a lot of background noise or a place I can easily visualise.

      Good spatial awareness is essential for safe driving, and as you pointed out a lot of people drive with one hand anyway, so I wouldn't be surprised if the accident rate was equally high for people using hands-free phones. You could test this theory in a driving simulator by asking one group of subjects to perform a spatial awareness task (eg matching rotated shapes) and a second group to perform a verbal task (eg listening comprehension).

      I live in the city and spend a lot of time walking around. I have reached the point where if I see a driver on a cell phone I assume that they will not see me and I stay well out of their way. They are in a little world of their own with very little awareness of what's around them.

      The NY Times had an interesting article on this recently (Times Select subscription required). Researchers put video cameras in cars and collected information about what was going on in the car in the seconds before an accident. The result was that "driver inattention was the overwhelming cause of the crashes in the study."

      My own opinion is that conversations inside the car are less distracting than cell phone conversations because the second party to the converstation is aware of the situation outside the car and knows when to shut up or to wait for an answer. The person on the other end of the cell phone conversation doesn't have this extra input and so the conversation doesn't have the natural breaks for heavy traffic that an in-car converstation would have.

      Your anecdotal evidence is contradicted by studies that have shown automobile drivers talking on cellphones are as accident prone and unsafe as drunk drivers. Some countries ban cell phones and driving at the same time and make it an arrestable offense.


      My two cents:

      I bet if you take a survey of drivers who talk on their phones a large majority of them would say they are not causing problems. Just like you said about yourself. And most of them would be wrong.

      Also, I've had plenty of friends and coworkers call me from their cars while driving. These conversations all too often start with 20 seconds of meaningful content then degenerate into a half-assed gab fest where they are happy to yak away, somewhere in between bored, lonely and distracted.

      How about we be realistic and accept the fact that if you are driving you aren't going to be looking at the body language of your passenger

      If we are realistic, we can't accept that, because we know it's not true. We've been watching people talking to their passengers, even in the back seat, and turning around to listen to them. We've seen women turn around to smack their kid while driving in rush hour traffic. We've seen a wide range of human stupidity, and lack your faith in humanity, because we are not morons.

      Lots of people WILL do that. Some people can handle talking on the cellphone while driving - if something happens they will drop the phone and if it ends up flying out the window or getting lost with the cheetos under the seat, so be it. Some people can't. If you would advocate banning one thing, then you should advocate banning all these things, and only allowing passengers on public transportation. All other travel should be done using single-person vehicles.

      I don't happen to believe that, but here's another thought; I have [had - crashed it, while I was doing nothing but driving, BTW] an S-class mercedes. It comes with no cupholders, ostensibly because they want you to think about driving, and not drinking something. However, in the really real world, people who are parched are distracted, and not having a cupholder means I have to do extra work to support my beverage. Meanwhile, they gave me an ashtray and cigarette lighter, because smoking is apparently a god-given right. How is smoking not distracting?

      Basically, people will do distracting things while driving, and yes, talking to a passenger is one of those things.

Maybe the brain becomes more excitable because the study subject just got a phone call from a friend or loved one? Furthermore, does the motor cortex excitation show a "sidedness?"

      No, microwaves can penetrate the brain with very little trouble at all. It's basically transparent to them, but every now and then a microwave will be absorbed by a molecule and heat it a little.

      And then your brain cools itself back down the same way it would if it were a hot day outside.

      Obviously it's theoretically possible that a lot of microwave photons could cause a lot of damage by heating the brain to the point where chemical change occurs. Your brain can cool itself quite comfortably if the hotspots don't heat up at a rate any more than 1K per hour - I've never actually heard of anyone checking that this is so, but I would expect that this was part of the initial safety testing when cell phones were first introduced.

      (Note that microwaves haven't enough energy to ionise the brain like your gamma or X rays do - they work by heating molecules rather than by ripping the electrons off an atom to change the chemical structure.)

      That tells us everything we need to know. You're worried about something you neither have read nor understood, but you feel empowered to tell other people how bad it is despite your ignorance.

      Don't you have the good sense to be ashamed of behaving this way?

      Cell phone radiation is of sufficiently low energy that I am not sure it can even penetrate INTO the brain. I am not sure this has ever been conclusively shown.

      Oh nonsense. Anyone with even a passing familiarity with particle physics knows perfectly well that if it can penetrate several dozen steel or wood walls, it can make it through half an inch of bone. If you don't believe me, find your nearest cell tower, stand between it and your phone, and see whether you get a signal. That said, that cellular radiation can penetrate into the brain has been extensively shown in other animals, so unless you want to pretend the human brain is somehow different, then the reason you aren't sure is because you've never checked. A display of ignorance is not an argument against.

      The issue isn't whether it can penetrate. The issue is whether it will collide on the way through.

      I am a radiation oncologist by trade.

      I'm not sure I believe that someone who doesn't think cell radiation can get into a brain could possibly be a trained particle physician.

      So I'm a little outside my training here.

      Real radiation oncologists are required to understand particle physics and its interaction with organic tissue. Those physical systems are as valid at cellphone energies as they are at x-ray and gamma energies. You shouldn't be outside your training if you are who you claim to be.

      However, even some of the treatments we use only penetrate a centimeter or less, and these are much higher energy than radiation from cell phones, as far as I know.

      A real radiation oncologist would know that the primary determinant in depth of penetration is the wavelength of the radiation, not the energy, which is why you can operate your ridiculously high energy devices and get only an inch penetration, and yet why a microwave running on AC power can wholly cook things. This whole thing rings false: if you are who you claim you are, then you are dangerously ignorant of your own job, a job on which other people's lives depend. If you are who you claim you are, I very much hope you will attend new training.

      This study appears, at first blush, to make the error of...

      How would you know? You haven't even read it! ... to make the error of assuming that association of two disparate events demonstrates cause and effect.

      If you'd read it, you'd know it didn't make that error (it's called the fallacy of conjunction, which an educated person should also know.)

      If the brain is more active, their study design fails to prove that it is due to the radiation.

      It has no such failure, and if you'd bother to read something before you criticised it, you'd know that. Of course, as a purported doctor, you should also be familiar with single-blind testing, which is in what they engaged, and whose specific nature is to eliminate the problem you're pretending you saw in a document you admit you didn't see.

      Maybe the brain becomes more excitable because the study subject just got a phone call from a friend or loved one?

      The subjects weren't receiving calls. Read the paper before criticising obvious falsehoods.
