As much as I love engineering, an unlimited race on current tracks would probably unwatchable without slow motion (and then what's the point?).

it would look like this, except faster;

would be great though.

A race like that would be kind of cool but then the human focus would be on sweaty dork engineers and not dashing playboy racers with lightning fast reflexes.

hey, I'd be a dashing engineer if I finished college.

that aside, it's why F1 needs drivers...because I can still beard out over millimeter changes in chassis design while normal people can obsess about stupid shit like if a driver has a nice mindset for a race or if they're going to lose the next 5 races because they didn't win the last one, and what their focusing on going into this race (hint; it's always winning and getting maximum points for the team)

@MPCG, actually, Money is a bigger driver of technical restrictions than driver safety. Without them, basically the team willing to spend the most money would win every year, and drive all the other teams from the sport. Basically what killed Can-Am, where Porsche was fielding a 1300hp car and completely dominating all the other team, to the point that they all pulled out. A technically unlimited series would still need a budget cap.

I think f1 is pretty cool but I prefer the Le Mans series. Especially the GT classes with the suped up stock cars. The new corvettes, the C7.R is a mean looking son of a bitch.

money is a driving force in another way; race track owners.

a retardedly fast racing series on an existing track would need massive upgrades to race track barriers to keep cars from just shooting through them (or tumbling over them) into the spectator stands. IF spectator numbers don't justify the spending, there would be few (if any) tracks for the races.
