I dont think its a good idea to ban anyone. Our MR2 community is inclusive. If anyone misbehaves on the track, they should be black flagged immediately and if bad enough, banned for the rest of the event. From memory, Grosso probably should have been taken off the track during the day and told to cool it instead of it only becoming an issue after the end of the event.
Let's start afresh and make the next MTC the best one ever!
