while I generally agree with your point, that new cars with great braking, enhanced safety and in perfect technical conditions are safer than average, I'm not entirely convinced if BMW is the right make for this kind of examples

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.
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.
