I'm always surprised how fast people on here say "Get a gun!" "Get a CCL!" Does anyone believe that having a gun or a CCL will help in any real way with the problems that this cyclist is having? Is he going to be waving his gun around as he rides? Is he going to pull it out every time somebody yells at him? Why are so many people deluded into thinking that having a gun is the answer to any problem involving personal conflict?
My opinion for the poster: See if you can find other cyclists in your area. Band up, create a unit. Push for change: bike lanes, law enforcement, public education around cyclists and their rights on the road. Things won't change fast, but they will change. The city I live in is an example of that. The rising price of gasoline will also help, once we get past the tipping point and folks start need to be thinking that cars aren't always the best way of getting from point A to B.
