I just find oval racing very boring, at least with BF1/F08, dont think ive ever seen a server using any other cars... I just don't feel the pressure and excitement like i do on the regular tracks. When i race on other tracks it just feels more immersive and exciting for whatever reason. It gets my heart pumping sometimes in a heated battle, that just doesnt happen on oval, for me at least.
People say theres such close racing on oval, but theres also close racing on all the other circuits/cars except maybe the BF1. Even with that ive had many very close races, just driving that thing around a track is INTENSE.
Anyway, i just don't care for oval racing (in LFS or RL), but to each his own. This game is about racing and having fun, so whatever cars/tracks do that for you, keep on doing it
