I know just what you mean. When I'm karting well I know what every part of the kart is doing down to the tyres on the tarmac, and you can just sese the limits. I also zone with other things. I was using scalextric and my eyebrows would move down the further I pulled the trigger, so decelerating was funny, because my eyebrows would shoot up. And when I played GT1 and GT2 on ps1, I would zone even though I didn't have any feedback. Weird.
