It is also not reasonable in any way to charge persons to leave their homes (currently the case anyway). That's morally repugnant.
Yes. Me. I pay for it
Care to expand on your comment, it currently doesnt seem to have a purpose that I can discern.
I live in a far more rural country than your own (Ireland) and Dublin city centre is choking on suburbanites' cars and hgv's. Those same suburbanites vote down any cycling improvements in the council. I think it's morally repugnant that I'd be terrified to let my kid ride a bike to school so you can have easier motoring, and expect me to pay for it to boot!
I ended up leaving Dublin in the end, bitter at its catastrophically weak approach to cycling and tired of drivers being jerks on the quays.
No it isn't.

Look out the window in z1 and you will see that it mostly is already.
What will you do regarding the person's who live in those zones? Will they not be allowed to drive?
