On mirrors on the left and the right
Long ago passing a small read "sport" car I stopped and asked the driver if he had lost the left side suspension as the car was leaning to the left in a very odd way. Apart from not beating me up the guy explained that the fuel tank was on the left to compensate for the (English) driver sitting on the right but now converted for a right side traffic both the driver and the fuel tank where on the left and that the car looked sound only when empty and parked.
I hope Alun Taylor will by now understand how so suddenly there is a mirror only for the driver.
For a long time my opinion about driving on the left or the right was "whatever" but now with navigators and touch screen stuff it's quite obvious (unless you are left handed) that driving on the left is the dumber choice.
So what happened in dear old England. Only the Swedes decided to drive on the left, but even they came to their senses and changed one summer night 1950 and something in a very orderly manner.
Was it the French and the Germans far ahead with automobiles, The French like with the metric system. Even back in time with a shield on the left arm and a sword in the right hand traffic on the right side was the obvious choice. Was it the "not invented here" or just the Great in GB or lawmakers on horses.
Never mind and looking at the bright side nobody remembered to alter the order of the pedals.
