But aren’t Indy Cars specially designed, with all the important stuff on one side of the car because they only have to turn one direction? In this era of cost cutting, F1 teams aren’t going to be designing new cars for a single oval race per season.
But, what I’ve always thought would be a great idea is a Figure of 8 ‘oval’, like that one off Mario Kart. That’d mean the cars would have to turn both left and right, there could still be high speed laps and banked corners, and of course there’d be a crossover section and thus some elevation changes. But, as far as I’m aware no such circuit exists, so it shall forever remain a pipe dream of mine
