Ludicrous Speed Bunny Hopping on Cyberpunk 2077

You can do this forever as long as you don't try going down any hills because at this speed you are likely to cover extremely long distances, which the game then determines to be "dangerous" falling (and therefore stops the player and gives them some damage). Normally going downhill speeds you up...but in the Cyberpunk universe, going uphill speeds you up while going downhill stops you completely.

Another weird detail is that when you travel at these speeds, objects spontaneously blow up and get destroyed (cars, trees, random doodads), which seems to suggest the devs intended random bad stuff to happen in the background if the player is speeding.
