I’m still fuzzy on it - the only way i can see a driver-less NASCAR vehicle crossing the finish line w/o the driver is if a yards-away accident happened - and i can picture the team/driver/car being declared the winner if it occurred so the vehicle crossed first since the odds of it not inning w/o the accident would be pretty low...but not impossible....might have to see if NACSAR has rules on the subject.
I can’t imagine how it could ever happen either. Just asking or wondering what if it somehow did.
