Interesting one coming home just now - was about to overtake someone on provisional plates when a car coming the other way flashed their headlights warning style so I held off - in the middle of the next set of bends was some kind of incident/crash couldn't see too clearly in the dark what had happened but half the verge was in the road and a smashed up car in the middle of the road. Might have had to brake quite hard at normal speed but sticking behind the provisional driver we were going a fair bit slower than normal - would have been more ideal if the people waving their phones were doing so before the corner rather than in the middle of it :s
