GENIVI: moving an industry to open source

- How is the drop in usage measured? Self-reporting? If so, there might be bias there.
- Is age factored out? I would think teens are more likely to flaunt those laws and are at higher risk anyways.
- In-car navigation systems and the like seem to be rising in popularity as well. Maybe there is some cancellation there?
Really, a decrease in the percentage of the rates due to cell phones would be the interesting numbers.

A) everyone is ignoring the law
B) cell phone use may not have been as much a factor as people thought.
In one of the links, they were reviewing the data from one of the early studies that showed that cell phone use was so horrible. They found that when the study was comparing "accident" days with "non-accident" days, they didn't account for the miles driven. If they changed the calculation to be by miles rather than by days, the rate of accidents with cell phone use was 1/5 the rate calculated in the original study, bringing it down to almost the accident rate for non-cell phone use.
In the other study, they did question people on their cell phone usage, and then had them drive the same route. They found that the people who reported high cell phone usage had many other driving habits that made them more likely to get into accidents (higher speeds +5mph, 2x more lane changes, etc), raising the question of if the cell phone use was the _cause_ of these people tending to have higher accident rates, or merely a _correlation_ with their other driving habits. This is just looking at the more extremes (use a phone frequently, and almost never use a phone), so it's hardly definitive either, but they are counterpoints to the "Cell phone usage is as bad as drunk driving" drumbeat that we ahve been hearing, so I thought I'd mention them.

Also, if they are cracking down on no-phone rules, are they cracking down on all other questionable driving habits as well? if so, is it possible that that part of the crackdown is the cause of any decrease in the accident rate?

Of course, it can be a result of the general crackdown. However, phones are clearly a contributing factor in a significant number of sever accidents.

I don't think that anyone disputes that some people drive significantly worse while talking on the phone, or that this results in some accidents.
The dispute comes when you assume that banning phones will significantly reduce accidents.
So far it appears that this isn't the case.
P.S. A law against something bad that everyone ignores is worse than not having a law against that same something, it encourages people to think of the law as something that doesn't really mean much, and it leads to people looking at cases where laws are enforced with the slant of "why were they really out to get that person"
Talking while driving

Personally I think that the cellphone laws is not a good idea; one must exercise extreme caution when talking while driving, but also when talking hands-free, smoking (those who do), changing the music, talking to your spouse, seeing an accident nearby, and any other condition that diminishes your attention to the road. Since those other things are not going to be forbidden it makes little sense to fixate on cellphones.
I think that the worst habit is filming a movie while driving; those actors that look to the passengers for minutes on end drive me crazy.
