From the cab - a HGV drivers view

• Some form of compulsory training for cyclists (Flame me, but the idea that anyone can pick up a bike, without reading the highway code, and go mingle on the roads in central london is frankly ludicrous, they put themselves and others at risk, and if drivers knew cyclists had some kind of test, they might be a bit more respectful)
  
  

The problem being that all bicycles would then need to be licensed in order to enforce the CBT, which is gunna cause a whole lot of fun for everyone. Have any other countries done this?
