The same could be said for keeping a helicopter in z1, but obviously that would be silly.

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.
