@@slivkiF You have to get out of the car, shoot it until gas starts leaking, start driving towards the cutscene trigger on the railtracks, dive out when you're kind of in the middle between the tracks and the road, cap your fps to 30 right after you dove out of the car, shoot the gas trail close to the car (but do not hit the car), get back into the car and start accelerating. When the mission fail screen appears, you can uncap your fps, retry, and hold Shift+S+D to run away with Trevor as fast as possible.
As no one has replied I’ll give my probably flawed answer, I believe it’s a “jump script” thing that can be enabled in project 1.27. I could be very wrong tho
