Basically the car ban proposed is a ban on all passenger cars, including personally driven company or government cars, within a determined distance from the city centre, in major Australian cities perhaps 30-50 kilometres based on suburban taxi zones. Practical refinements would need be implemented ad-hoc. It's not a ban on private car ownership per se, but owners would have to garage cars outside the city ban boundary and use transit, taxis or taxibuses to and from their garage for country driving excursions, and country visitors leave their cars in the same garages.
Urban drivers of delivery, transit, emergency vehicles etc. would largely be professionals, except perhaps for tradesmen, housecall doctors and such; but all would need pass much stiffer training for licences, and face lifetime licence revocation as minimum penalty for culpability in collision fatalities. Regarding those corporate or government cars that remained real restrictions on use should apply, they should be required to have a professional driver permanently with the car, bringing market forces into play and making these vehicles more extensively utilised and smaller in number. They should be required to access private, non commercial off-road parking at both ends of their journey, further discouraging their use. All free and commercial car parking spaces should be abolished within the ban area. Portions of current driveways should remain as small bays for emergency, taxi and delivery vehicle temporary parking.
Vehicles not banned would be: human powered vehicles like bicycles and low powered motorcycles or wheelchairs/trikes; business vehicles used for service, courier & delivery but not used for commuting or motion about the city; buses engaged in charter, intra-corporate shuttle/commuting as well as public route service; emergency or police service vehicles; taxis for the disabled or politicians, celebrities, or private people avoiding public exposure. Motor vehicles would need display business or disability based registration stickers, road standing would be limited to setdown/pickup stops for buses and taxis, delivery, service and emergency vehicles, dedicated taxi ranks would probably remain.
Transgression would entail a penalty of at least arrest exerting whatever force necessary to stop the vehicle, with vehicle confiscation and licence revocation for multiple offences. Preferably infringements would incur criminal rather than financial penalties, months licence suspension and a few days jail for first, more jail and longer licence suspension and vehicle confiscation for second, licence cancellation for third. Means of implementation would be geographically and temporally gradual: first city centre, then inner, then middle, then outer suburbs; timing being staged with months of warning, months of fines, before the full ban made transgression an arrestable offence.
Supporting legislation and action would:
- banish commercial or free car-parks to the urban fringe,
- stipulate road reclamation and sale procedures,
- abolish building codes requiring provision of car parking spaces,
- compel retailers to provide and cross subsidise daily delivery within determined geographic bounds,
- remove company car tax deduction and include transit fare tax deduction,
- ensure fibre optic cabling was universal.
