Better indicator for when the car is bottoming out. Especially on the bumpier tracks with elevation changes, it is easy to bottom out with some of the prototypes/formula cars and enter an unexpected spin even at low cornering speeds. If the player does not realise what is happening, they might think the car is broken or something is wrong with their inputs. It is possible to see this from the telemetry HUD display by monitoring the ride height, but driving with the full telemetry HUD on is too distracting to be practical. Real cars give very strong sensation when the car bottoms out and this could be somehow replicated by a combination of sound, visual and FFB signals.
