Hey, thanks for the detailed review. It was a interesting read for me, for sure.
So, by the lock-in-place mechanic, I assume you must mean when the car rolls, tumbling out of a drift? Yeah, well, in the code I took away all steering then because, I figured, tires not touching ground, no steerage - but maybe you're right and I was thinking of it too realistically. Perhaps a sort of diminished control would be better instead for the player's feel, until the tires get a grip back onto the ground. Will have to think about it.
I like your idea for a wave feature in particular. Thanks a lot for your in-depth feedback.
