Note that currently cyclists aren't included although they are the worst at suddenly veering off the footpath onto the crossing.
gross exaggeration here and know way you can backup this without surveying every incident not just the ones you see. Apart from that I agree with everything you put but not sure why you changed the topic to include cyclists.
OK to avoid having to get into statistics that are usually years late I'll change that to "amongst the worst".
I'm not changing the subject of pedestrian crossings just including other users. My route in and out of Wellington is alongside a fair amount of shared pedestrian/cycle way. Maybe it's time to video a few trips in and out.
