I agreed with everything up to this point, but there is a dynamic you haven't covered. Actually, if you ask joe public, would he prefer to be stuck in traffic, pay the monthly payment on the car, insurance premiums, mechanics fees, MOT, new tyres, etc etc, OR live in a deliberately planned town that makes walking, cycling and other forms of shared public transport practical, get their groceries from the town market rather than the mega-super-fantastico (rip off) supermarket, they would be quite likely to opt for the latter. But they don't have the choice, because motorcars dominate the high street of every village and town in the country, thanks to government policy.
We have a great deal more agency about where we live, work and where we get our groceries than we think, but there are limits and constraints placed on us by the motorcar. You may need one to remain competitive in the workplace and lead a 'normal' life. But did anyone stop to consider that 'normal' isn't necessarily the best way to live. There are winners and losers of all policy decisions, no doubt that disabled or elderly people benefit greatly in terms of mobility as a result of the motorcar, but at what cost to society? Kids can't play outside their own front doors, and you can't walk to the shop without inhaling illegal levels of PM2.5.
This is why looking at the alternative models presented by other nation states is crucial to breaking free of our own mental chains. Note that places like the Netherlands or Denmark don't make motor transport impossible, one can still undertake intercity travel in car. However it makes more sense to use the alternatives for most people for most journeys, they have the choice about where to live, be it closer to work and amenities they frequent. My own grandparents are Dutch and live in the capital, they drive everywhere, because they are too old to cycle, or so they think, but a least they have the option. There is a way the two modes can coexist, but current governments don't get it. The government is the last person I would Trust to educate the public on the benefits of cycling, they have failed up to now for a reason.
We have backed ourselves into an all mighty corner with the motorcar as the supreme form of local transport, it's an easy corner to get out of, but there are powerful lobbying interests who want to protect the "freedoms" (actually chains) provided to the proletariat by their cars. You only have to look at the faux freedom presented to the consumer in car advertisements to see what we're getting at here.
