I'm a very courteous driver, I was in Notts a few years ago and I spotted a disability scooter and driver waiting to cross the road in the distance. I slowed right down flashing my lights for him/her to cross, got closer and closer, still not taking my invitation. Got right up to the vehicle and it was indeed a scooter with a dummy on it advertising the disability shop adjacent, the prick who owned the shop must have put his promo on the kerb side for a laugh, can't imagine I was the only one to fall for it.
