The solution to people cycling faster than your taste on the 'superhighways' is the Green Wave - this is a system where the traffic lights change in a sequence where people cycling at 20km/h can continue through the whole series of lights without ever having to stop at a red.

It's a nice compromise - 20km/h is nearly double my own normal cycling speed, but is under the 30km/h that training types would go at. And as cycling takes over from driving (as it is already, though this is masked by the fact that a single driver has a whole car around him or her), it will be possible to widen cycle lanes and allow a single lane for the 20km/h cyclists and another for slowpokes like me.

The 'arrogance' charge always makes me laugh, encountering, as I do daily, shouty drivers, registered-blind drivers, drivers capable of steering their vehicles by telepathy while posting on Facebook on their phones, drivers freshening their makeup, drivers smoking, etc. Sometimes doing any of this and others fatally, like this woman who turned around to take a tag off her child's toy toy while driving, and killed a man.
