Quite right. My own post wasn't very clear. What I meant was cyclists don't pay directly as they don't pay rego or fuel taxes. But they dont wear out the roads, and they do reduce congestion so in some ways they help the road wear. But as per my previous link there is a hate by motorists to cyclists as far as more cycle ways appearing has raised.
On well designed road system cyclists ease congestion. In badly designed systems (e.g Island Bay) they can cause congestion including holding up buses.
Out of interest how do they hold up buses?
