It's odd that so many of the comments on the self driving threads make this assumption that drivers of expensive cars are safer than drivers of inexpensive cars. It is just part of the classist bias that attaches virtue to wealth? Or is there some data that suggests that a Mercedes driver is a better driver than a Kia driver?
It's a combination of things. For instance drivers are statistically more likely to have accidents at 18 than 50. Drivers are more likely to have an expensive car than 50 than 18. Being less financially secure often means you are trying to keep an old junker with crappy brakes going when young.
Also risky behavior like speeding, DUI, driving aggressively, passing when unsafe, etc are generally more common when young.
Sure individuals vary, but just look at the cost of insurance to verify.
I don't know of data, but the high cost of a Mercedes over a Kia means that the average driver is likely to be older and young drivers are a known risk factor in accidents.
