Two days ago a cab driver leaned out of his window and helpfully observed that I was riding in a bus lane. I'm not sure whether he thought this was news to me or what.
Best one ever, although not strictly a one-liner, was on the Dumb Run (the first one, I think). 1:30am or thereabouts on the outskirts of Cumbernauld, we'd stopped under a road sign to check the map and this car screeches to a stop with Aerosmith blaring from inside. The driver winds down the passenger window, scoots across the seat, leans halfway out of the window and regales us four astonished cyclists to 30 seconds of I Don't Wanna Miss A Thing before retreating like a snail with a poked eye and screeching off again.
We get some absolute classics on the Dumb Run. Scotland's central belt in the wee hours of a summer Sunday morning is one of the most surreal places in the universe.
