Several other opinions are in the linked story. Haven't read them all, although I did see one comment that noted that EVs are heavy--how and what is a 6,000 pound EV going to do when it crashes at race speed, into a retaining wall...or another race car on the track? The cars NASCAR raced in the '60s didn't weigh more than 4.000 pounds.
Another opinion states that running EVs will be the final nail in NASCAR"S coffin...
