Well Ria, just think of all the times when I'm sitting there in the freezing pouring rain. Paying my price for my faster journey...
Also metal plates and rain make for exceptionally dangerous riding. It's a hazard without all the people sitting in comfort getting annoyed that those who brave the elements and the lunatics get faster travel.
In a month or so I'm going to be broiling slowly in my black jacket and trousers as all those "irritated motorists" sit in their air conditioned cars...
I'll take the trade.
