It's been tried so many times but no one will ever listen.
Things to remember:
Motorcycles are dirty, dangerous, smelly vehicles ridden by unwashed and uneducated people who have criminal tendencies - at best.
Someone has to pay for the eco, tree hugging people so it may as well be us.
Next time you get a contemptuous look from a driver who is really too old to still be safe behind the wheel, just smile as you are subsidising them to go onto the roads and cause havoc. I get scared at work on a daily basis by some geriatric who shouldn't be at the wheel.
Remember the golden rule:
If the driver is wearing a hat of any kind keep away from them.
Some examples:
Baseball cap (either way around) - boy/girl racer
Flat cap - Centenarian who can't see and whose reflexes are slow. Likely to stop suddenly without warning as always lost.
Floppy Sunday best hat - Old granny who learned to drive in the war. Drives as though it is still 1945 and smiles a lot.
Stocking mask - Cash in transit robber making a getaway.
