Riding in this morning, a DHL lorry sits patiently behind me in a new 20mph zone, waits to overtake whilst not cutting me up near central islands, and passes with the Highway Code endorsed spacing.
I catch him at a garage, cycle up and say thank you, and I wished all drivers could drive as professionally as he did. His reply? His first thought was that I was going to have a go at him. And he replied that he rides this road to the depot each morning and know what it's like.
So that's the answer - the Met's Switching places that gets cyclists into lorry cabs, needs the opposite - lorry drivers (and of course car drivers) on bikes to see what it's like being brushed by wing mirrors.
How do you thank good drivers?
