Ramps

[Fry]

If that check happens, you'll hit it hard and fall off.

I'm assuming you're talking about bike v. car here, in that case you'll only "hit it hard & fall off"  if you're moving very slowly.

if you normally drive it's hard for someone to keep freezing him. If he/she chases you and manages to do it, he/she has speed so can't directly do it again. Easy to escape from, imo.

That's the point. We're trying to eliminate people who stay or ramp just to freeze other cars without going over them.
