@Michael_Rush There are lot of things wrong with physics in this game. This isn't a racing simulator. It's an arcade racing game. Meaning, it's supposed to bend the rules of physics here and there. Losing a race over something as uncontrollable as riding over a bump, shouldn't exist. You should lose a race from having a slower car, face-planting corners, drifting improperly, drifting too much, not racing on the road provided and getting sent flying from the road provided. Especially when most of the time, those "bumps" aren't visible. You just magically get thrown in the air. For the visible hills, like going up ramps, and huge hills, I expect to fly, but I'm flying on straight, flat roads.
