Hey, thanks for your feedback.
I have just released an update (and accidentally deleted the original 1.0 game release 🫠) addressing exceeding track limits ("I can't stop flying out of every turn. Maybe the start could have walls so you don't have to go through the menu every half a second? "). Now instead of instantly getting disqualified you will get disqualified after receiving certain amount of track limits points. In terms of engine modes, I have still no idea how to make it less complicated, but once I'll know how to make it better I will update the game.
