There was a lot of talk about this among ordinary people when I was over at the weekend, just in the context of the Cycling Week, and the disruption it had caused. Needs to be carefully watched.
I think perhaps the times and places of the road closures were perhaps part of the problem. TT is always the same dates and places, so no nasty surprises.
It will be interesting to see how they are about the Manx Rally this week.
