I'm sorry to hear that, but I don't think that was quite what Laura meant...
If you're talking about distractions, then we should also consider cell phones, fast food, conversation and ICE/GPS as potential killers too.

Actually a friend of mine has such a phobia of any small and multi-legged - spiders, ants, centipedes, you name it, that she vacuums her car daily to try and avoid accidents, as her reaction to seeing a creepy crawlie is to let go of the steering wheel and duck. She's still had 2 ant-related accidents in the past 5 years though, and I'm trying to persuade her to see a phobia specialist so that she can at least gain enough composure to stop the car safely..
