Dangerous cyclists? not!

If you are doing 20/25/30 in a 30 zone and a pedestrian decides to step out in front of you when they're only 5 metres away from you, an accident will most likely occur. It is unreasonable to expect a driver - any driver - to be able to react and bring the car to halt in those circumstances.
Each circumstance would be different, and different inferences and conclusions could be drawn.

To simply claim that the pedestrian has right of way as soon as their foot touches the road surface is ludicrous.
It doesn't work as a one-size-fits-all rule, no.
