I second including drifting
It somehow feels like the steer directions when going in reverse should be flipped. I can't point to a specific game because it's been years since the last time I played a game with vehicles like those, but it's stuck in my head, gamer sense.
It's weird not being able to kill infantry when shooting a shell at their feet, but only from direct impacts. I think the precise hitbox is for accuracy in detecting the zone you hit in a vehicle, but perhaps it would be nice to add an infantry-specific hitbox that's much larger, for sharpnel and shockwave.
self destruct VFX should be a different color from repair
Vehicle parts destruction is a neat.
