Wait at lane one !
Good old BRITISHNESS that's why we "don't" jump the que and go ahead up to a free lane, we don't jump que's.
Having said that
I think it may be a good thing if shotgun starts became to norm, as it makes better use of the facility with all lanes being shot from the beginning of the comp. BUT if you think about it "someone would have to administer it" wouldn't they !
So those that want a shotgun start how about offering to organise it for the rest of us !
I would go along with that !!
