(can you imagin NASCAR with no engine noise) ???" lol - I can't -
And...how about the pit stops...20 minutes per to charge the bats. unless they come up with a bat like what's on your bat powered drill that they can just change in seconds. Something like a bat that runs front to back in between the left and right wheel...they could line up a hot bat in the pits...car comes up...hits the new bat that pushes the old bat out the back of the car in the process loads the new one. Zip Zap....whuuuurrr and we're racin.
