If you drive more you are more likely to be in an accident, that's just how roads and accidents work.
replySure they might be better and per unit of time they drive they must have miniscule amount of accidents.
But if there's a 0.001% chance per hour driven, then over enough hours a few accidents are inevitable.
They don't just add more hours of driving they replace a small amount of risky hours for a lot of hours of low risk if they change location/job.
replyAlso Drivers are generally less likely to die in accidents in urban areas, on high ways it's different.
replyPedestrians are a lot more at risk. So that's unsurprising that annually 1/2 taxi driver might be fatally injured in one.
But I would assume the ratio of other drivers to taxi drivers would be high enough that this number should be zero as well.
