Milan has about .5 cars per capita, compared with .3 for london. Italy is one of the most motorized countrys in the world at .72
Mexico has a expanding motor fleet .3 growing at about 7 %/year. Greater Mexico city, pop 21 mill, has gone from about 3.1 mill cars 2000 to 9.6 mill 2018 - thats a yearly growth around 16.7 %. Mexico city is considered the most traffic-congested town in the world. Milan is one of europes most polluted cities.
These are car crashes, not good examples - although i suppose its possible to learn from disasters and the handling of them.
I couldnt find any reliable statistics on car-free towns and cities in the alps...
Your long term goal is to ban private cars from the planet. I can agree with that, property is theft and so on. I suppose we still will need some vehicles - ambulances, fire squads, trucks, buses etc. Where would that leave us re cars per capita? .18 - the worldwide number of today? More? Less?
What would be your short and medium term goals, for the UK and the world? Starting from today with 73 million cars produced yearly and 1.3 billion vehicles on the roads, car travel making up 85 % of all distance travelled in UK, .62 cars per capita - where will we be in 5, 10, 20 years?
And how do you intend to get there?
