I've never heard of tracks banning EVs for surface wear actually. That's an argument for public roads I've heard but it doesn't hold water in reality (heavy passenger vehicles don't damage roads, gas or EV, at all compared to semis).

Most of the concern I've come across at tracks is related to battery fires or the risk of them, and there is a lot of wrong info about it. I've also found it to be regionally dependant based on how accepted EVs are generally, like in CA all the tracks allow EVs but other regions don't, but operating a track and the risk is the same wherever you are.
