Watch the video on the BBC's website. The old biddy is nearly run down, because the evil road planners are bastards. Two observations:
- She is walking at the same speed as the man in front. The problem is that she dithered for ages before starting to cross. That's hard to design out.
- There was plenty of time for her to cross anyway: it's just that the chav in the Corsa decided to try and run her over while she still had priority on the crossing (you can only drive over a crossing when the yellow light is flashing if there's no-one on the crossing. Many motorists take a similar view even when the light is red).
Well done, BBC. Another triumph by your news department.
