Comment Re:Did the accident rate increase? (Score 1) 367
Just to play devil's advocate, maybe the accident rate would have gone down even more of people weren't using cell phones.
Also, there are 3 things worth measuring: number of accidents, number of injuries, and number of deaths. Cell phone use might lead to a rise in #1 but improved vehicle safety features might lead to a decrease in #2 and #3; enough to cancel out the increase in #1.
Many factors could influence any or all of those numbers. Example: My 2012 car has like 14 airbags: steering wheel/dash, A-pillars, and even in the seat itself. (We can't use seat covers.) They won't do a damn thing to keep me out of an accident but they'll lower injury & death rates. (Unless they give me a false sense of safety and cause me to take more chances behind the wheel because hey, I've got airbags, I'll be fine. In which case they could raise the accident rate.)
And the numbers could, possibly, get REALLY weird. Imagine a feature that reduces the number of low-speed collisions, but is no help at all in high-speed collisions, where all the deaths are. So instead of 100 collisions and 50 deaths, you have 90 collisions but still 50 deaths -- fewer collisions overall, but the deaths-per-collisions rate would actually increase. So yeah, lots of things can happen with statistics.
I'm too lazy to look at the moment and see which number(s) they actually studied. The slashdot headline says "crashes" which means there's about a 50-50 chance that's what the study actually says.
