The suspensions were softer, but the terrain model has too few vertices and the car was shaking a bit too hard. You will be able to adjust the suspensions in the template version, adapting them to your levels.

The opponents slow down when they approach you; however, if you don't move out of their way they will hit you. They run on predefined paths, so it wasn't possible to make them avoid the player completely, especially in a level with narrow roads like this.
