Make collisions with obstacles on the side of the track less punishing

[Alayan-stk-2]

It is fine that a player making mistakes and hitting things loses speed and time. However, sometimes it is too punishing, especially for less experimented players that struggle more with using reverse properly.

The main issues are caused by :

• Low-height borders leading to strange collisions (e. g. Candela City)
• Protruding walls, where the player hit and cannot start moving again without using reverse (e. g. Old Mine, STK Enterprise)
• Complex obstacles on the off-road, with issues similar to the protruding walls (e. g. Black Forest)
• Getting stuck without rescue in some off-road parts of some tracks.

Some of the improvements should be done in track design, but some other improvements require tweaks to physics to make it easier to restart driving normally after some collisions.
