I read at work(can't remember the source) that some states have started painting wider lane markings/lines in order to increase visibility(of lane markings) and, thereby, make the roads safer somehow. I guess it's supposed to keep traffic corralled more effectively? Anyway, I was just wondering what people with cycling/driving experience on roads with these markings think it helps, if anything. Florida(6" wide lines) and New Jersey(up to 8" wide lines) were mentioned in the article. I think the widest our markings here get are 4"(that I've actually seen). Does it really make the roads safer?
