They are opposite Paul Simon, not Yasha, where the guy was run down last year. I was walking down GL today and sure they were really visible, but with traffice grinding along I was not sure that you needed 150m or notice that the lights had changed. It seems to me that you have a bigger problem with people trying to get across the lights before they change so they can make sure they get to grind 25m further up GL as opposed to wait- certainly this seems to be the case from my 2 forays across GL this afternoon.
Yes I've seen a lot bicycles going through red pedestrian lights. I've almost been hit by a bike twice, once on a Zebra and once on a pedestrian crossing which was on red (for the traffic, green for the pedestrians). Luckily I saw them in time and I stopped - they didn't.
GL seems to be a magnet for bad drivers, far too much traffic forced along this stretch of road. Too many cars doing 3 point turns when they've finished their shopping.
