If a bunch of lunatics buy the car because it is fast, and kill themselves, that doesn't necessarily affect my safety in the car if I'm buying it for some other feature and don't intend to drive it dangerously.
I think gathering the data to judge who's a lunatic is quite hard and fragile. Finding proxies like past infractions record would be already hard enough to compile at scale, I can't really derive a passable methodology that could tell you what you're asking for.
At least the data informs others that perhaps it's good to be cautious around Teslas, not very much if it's a safe purchase, and they state that it's a safe car so I don't see the hangup you had about it on position of a buyer.
