One I spotted a couple of years ago around Pinner:
- dustbin truck collecting dustbins - hazards on
- car approaching goes to overtake it
- dustbin truck moves on (hazards still flashing, not indicators)
- van coming the other way
- driver realises he's not going to make it, with nowhere left to go
he totals the keep left sign in the central refuge

I saw the start of it as I cycled by in the other direction,
heard the end of it, luckily the only casualties were the keep
left sign and the driver's pride.
