F1 Valencia

The reason you can't force anyone off the track is simple - it's dangerous. Ideally, every inch of the track would have an armco barrier right at the edge of the track. Obviously in the name of safety, a lot of the corners will have non-armco'ed boxes so that a racer won't plough straight into a barrier, but the area should still be treated as if it is cut off by barriers - i.e. deliberately forcing someone into such an area is seen as the same as deliberately forcing them into a wall.
