I understand that the recent incident has concentrated the C of C's mind, but holding riders up on the mountain for several hours on a wet day is surely not a good idea ? the course naturally has sections so if the travelling marshalls or police stop movement into their section after a period of time ie 30 mins, it would be safe to move the riders clockwise section by section like the travelling marshalls move now ? If there are riders trapped before the incident they would need to wait OR travel reverse direction under travelling marshalls supervision.
I don't know how the course car and rider collided but it was a freak, and I think this is a little OTT, but understand that something has to be seen to be done.
Having said that I wish Steve Mercer a swift and full recovery.
