Multiplayer penalties

The penalties in multiplayer racing is a joke and they need to be addressed. Ive had players smash into me and i get a penalty wth. They need to implement a tougher penalty for the smash bros in this game ive been spun out in the grass and they get a 2 second penalty yet it takes me 20 seconds to get back on track. Forza needs to implement what other sim games do is if you spin someone out you have to relinquish the position and if you dont its a minute and a half penalty that should make the trash racers at least think before using you as a rub rail.
