I almost hate to weigh in to the fray.
Thompson weekly divisions did not have a stellar day first. The last two Tour events have also been woolly. The Icebreaker even had the big one in turn one.

Modified racing in general just has too many wrecks. The cars too fast? Equality in the field? Move instead of pass? No respect?
The MRS has a pretty good record of trying to promote racing clean.

It's not MRS but SK and Tour also that this happens. Over all it is not good for the mods.
