Run half the cars clockwise around the circuit, the other half counterclockwise.
Furthermore remove halos, wings, crash structures, and anything to do with electricity, because authenticity, soul, and feelings. Although maintain paddle shifters but randomize the signal (pneumatic now, don't gotcha me) sent to the gearbox so that the driver never knows what gear they're going to get. I have other good ideas to improve the racing but I'll stop here.
