Not if they use 'platooning'. Team Lead car sits in the middle of the pack, drafting like Andretti. Be much easier if it was just a driverless skateboard, RADAR/FSD maintains the millisecond spacing interval (<1 meter) that no human could ever hope to do for 2.5 hrs.
No Crashes? Maybe takes the fun out too, but hate to see any driver hurt, and it happens all to often (and not just on the racetrack).
EDIT: Think of it more as a 'demo' than a 'race', it'd have to be cooperative. More like a Team Time Trial at the Tour d'France than an Indy 500 competition.
Cheers!
