I doubt licensing folks to cycle will do much. This evening I was riding, came up to a red light stopped, as did 3 or 4 other cyclists. As we are waiting for the green, we are passed by another cyclist who goes right through the red. I heard folks mumble some not so nice words, but a motorist yells at us, "Why don't you tell your friend what a red light is". I asked the other cyclist if they know the guy, they all shake their heads no. I caught up with the guy about 7 miles later, he was my age. I asked him if he saw the red, he said yes, and said "If a cop is there I stop, if no cops I don't stop". I tried to explain why he should but he would not listen. That is why I doubt licensing would help, most of those that are the problem know better, and won't change until they are bug splotch on the windshield, or they get a ticket, and there are a few that would do it again even after being cited or hit. There are some things in life you just can't fix.
