As a cyclist, I haven't noticed anything like that. I suspect some internal bias towards EVs or against Elon or something is making you notice a pattern that isn't there.
they are bad drivers without accidents because everyone else is watching out for them.
If I see a Range Rover, Mercedes, Audi, BMW or any large pick-up in my rear view mirror I expect to be aggressively tailgated and I'm generally correct. This has not happened to me with a Tesla, that I can recall.
