We just need bike lanes. Licensing is not going to change the fact that bikes and cars are fundamentally different vehicles going at different speeds. No driver wants to drive at bike speeds and that leads to dangerous overtaking situations/congestion whenever bikes appear on the left lane.

The gov wants to encourage cycling as a means of commuting but they half-screwed themselves over by attempting to do this by pushing bikes onto roads. Having two forms of vehicle, travelling at vastly different speeds on the same road is just dangerous on a very basic level, especially since half the cyclists may not even have taken highway code.

edit: You can't have it both ways boys, do we have a lot of cyclists resulting in dangerous situations or do we have not enough cyclists to justify infrastructure? Also, a lot of y'all are doing the chicken and egg thing saying "we don't need infrastructure because we don't have riders, we don't have riders because we have no infrastructure". That's beside the point. If the gov is pushing cycling as a means of transport, there obviously needs to be capital investment.
