Would be nice to have like a speedometer or something for each car. It very quickly, becomes very hard, to tell if your car is acceleration capped or top speed capped.
Also as much as glitch does help speed up the game a lot. It kind of kills the whole idea of making your car go as fast as possible.
Since anything you do speed/acc-wise is shuffling decimals, while gaining glitch is a stacking multiplicative 2x. Makes it so the main thing that matters is the only thing that has nothing to do with what you're actually doing (going fast). If you wanted the same effect, but still rooted in what's actually happening on screen. I'd suggest having glitch instead relate to lap distance. So that higher levels = shorter lap.
It does also mean that your exact acc/top speed ratio needs change over time, to force you to change your strategy as you go along. While also being more thematically reasonable than 1 lap suddenly counting as 16 laps for reasons.
