I really like this design where a racing game is lap-based but doesn't have a start/finish line, and if expanded I think could lead to really interesting arena design where a player could tactically "skip" parts of a lap to return to later. The controls were indeed a little frustrating but I think are only a couple of minor changes from feeling good- (for me personally, I think being able to turn without forward momentum, and upping the rotational friction, would be all that is needed). I think the randomized obstacles were cool, keeping a racing track fresh with randomized elements is a neat idea!
