Well, if average human reaction time is a significant portion of the time it take for a car to get to 60 mph, then it would be hard to see why accidents wouldn't increase. Your foot slips and at least the car is totalled. It's not like high powered gas cars and motorcycles don't have this problem, with people who are not 80 and senile. People make jokes about Mustangs crashing at Cars & Coffee. People make videos of idiots in Lamborghinis crashing because they tried to do a burnout.
