You're asking if people showing up to NASCAR races are arriving in EVs, right? Basically, are NASCAR fans EV owners? Not sure how anyone could know that, but just doing some googling and it seems that have promoted events about green technology, including EV chargers, so it would seem that they expect some of their fans are aware of EVs.
If you are talking about EV races, NASCAR doesn't do that but there is an EV racing circuit called Formula E that is all electric race cars since 2014. There's also an electric off-road race called Extreme E that's been going on since 2021.
