In my pal version (i don't know if they fixed it, but if so than that's cool) I don't get 5 sec penalty when the AI car hits me from the back. I almost never lose any of the rallies too, so i really do not care, but i *Think* when the AI hits me he gets a 5 sec penalty because then i can speed from him like he was in reverse. I have to check it on a replay.
