Sure, but would you watch it for getting adrenaline rush from racing? At some point it would end up as who has the best "non-linear controller" wins (i.e. human is your non-linear controller now), then all of them will have it and all the tweaks will be in some optimization techniques and different objective functions.

And your objective function would have to feature penalty for "killing yourself" (well, do you want to rebuild your car after each turn? I guess not...), so I would expect the cars will be actually pretty slow due to this initially, like Google's own.

Human motorsports face the problem that all physical records were shattered and humans already crossed the edge of their abilities (i.e. driving 250mph on the ovals is the limit before drivers pass out)[1]. So yes, there could be something interesting for a normal human to see that robotic cars suddenly could push 300, 350, 400mph etc. But what would this do to human motorsports? Relegate them to 'meh' category, basically killing the whole sport as humans would look like kids from a kindergarten comparing to robots.
