Check out formula e. It is electric race cars and they can get bonus power by driving in a particular part of the track. They used to let fans vote to give cars a boost too but i think it's discontinued.
I think nascar already has a virtual banana peel. They also stop the race right before the end, then restart and hope for crashes then.
When they started redesigning the cars to be safer in the late 90s I’m pretty sure they were doing it because 80%+ of the audience at those races were there to see crashes.
Extreme E has boost, and is probably the most fun racing I’ve seen. Cars flip and keep going, and are lucky to make it to the finish line in one piece, lol.
Just finished watching the 24hrs of Daytona where they use that infield track layout this week. It's free on YouTube from IMSA!
3 classes of cars fighting for places through traffic for 24hrs. It's absolutely wild, and the commentators are definitely fighting fatigue with sometimes extremely random sidetracks too.
There are 6 road races on the calendar this year. 5 of those have been on there for multiple years. 1 is at an oval/road course. They have been running at road courses for a very long time, just in proportionally small numbers.
