There is a great deal of bias by the walkers and bike riders and it is not really relevant. I agree we do not need stripes BUT we do need some policing. The other day I came across a bike and cart accident. The first thought is to blame the cart BUT as I drove by (it had just happened) I noticed the bike rider who was on the ground pulling ear plugs out of his ears as he must have been listening to music, etc and did not want them in when the authorities arrived. Given this I watched today and saw 3 bike riders with ear phones in which is as I understand it is not legal? Lets agree that stripes would not matter if the bikers are using earphones to block sound or to hear music. The same would apply to walkers as they could not hear a cart or bike approaching? It would be interesting to know how many times the rider or driver or walker were using ear phones when an accident happens.
