I have no idea how anyone managed to smack this street furniture so hard, or what direction they came from to do it. It's a pretty straight 30mph road right there, and this is only one side of the dual carriageway. Never seen so much as a near-miss there.
I'm not sure I'd be waiting literally in the road here if my car had broken down. The continual strewing of the pavements on these flyovers with broken bits of cars, vans and lorries, large and small, suggests that smashes are pretty frequent.
