Most higher end vehicles (and frankly, I don't count Tesla as particularly high end, particularly not the Model 3) have similar stats, for a multitude of reasons (including but not limited to driver experience and time behind the wheel as a function of affordability of the vehicle).

Where's your data to back up your claim?

miles driven, not market share, is the correct comparison here (and even then you'd want to include many other covariates, such as where the cars are operated, socioeconomic status of drivers, etc, etc) if you really want to compare different vehicles.

~2% of new cars isn't anywhere near 2% of cars on the road or miles driven, and newer cars are safer in general.
