Would it be any better if they could go both ways... I think not. I saw a fatal at MGP time near Barregarroo... no cars... two bikes, one dead rider, and then another on the road to Laxey...that was in the 70s. Sorry, but I think it is the idiots who are the problem not the people who have at least tried to keep them all going the same direction. They are guests on the Island (mostly) and should behave accordingly... but they don't.
