I didn’t play MP because I don’t like dirty players pushing me off the track or blocking me. And I don’t want to slow down to avoid pushing other players too.
If I can create races that disable player collision, I can participate some form of MP experiences without the full tactical driving experiences. I don’t care about ranking either. So, if that is a concern, just rank me in a different category.
It is not much different than playing against ghosts. But, having real time interactions is still more fun than playing against recordings.
