I’d say tone it down a lot of some. I’ve had the AI literally drift right my car a few times? But I feel your pain, when you hit them, they don’t budge! It’s like doing tandems with cement truck? =)
I like the collision. They shouldn't remove it. If you hit the bot then I think you should adjust your drifting... Also the opponent missions are too easy and they should make more points in career mode.
