Back in the day, used to have a '72 Roadster - no grabrail or humped seat like that. Tried to impress a young lady I worked with, gave her a lift home after work.
Didn't realise there was a humpback bridge on the way into her village (Fladbury?)
She slid off the back of the seat, luckily being stopped by the rear light. I was more concerned by the damage done to the light housing...
