How would you apply vehicle behaviour (IE being able to go off jumps or go through loops) onto a character?

Yeah, something like that, but cancels out if you lose enough speed/don’t have enough to get up it in the first place. And by “speed”, what do you reckon i should change the values to? Acceleration is currently 500, and my max walk speed is around 40000.0
