SOLUTION! Go to steam, then go to BeamNG.drive, and click betas, and do old DX9 0.4.0.6 version before the BUSHES ACTUALLY DID ANYTHING, then you can race in peace. (exception to all the new features but I'm sure this bush is way more important)
Try to not cut corners and drive like you would In real life. Bushes IRL would rip up bumpers and cause damage at those speeds... Or Go to map editor and remove all vegetation
it would take quite a bit for a bush to "rip up" even a plastic bumper, and it also wouldn't slow a car down nearly as much as in game.
Well, depends what type of bush, I had a friend who got his bumper cracked and torn from the body on his Jeep from a well rooted bush.
