A big factor is that the urban population is much larger and tends to vote for things that make sense in their context, but any laws would also apply outside it.
So those in the countryside might be badly effected by a car ban imposed by urbanites.
It's a similar effect to the way policies tend to get made that are good for the middle class but bad for the poor.
This is exactly reversed, people in cities bend over backwards to adapt laws to work for people in rural areas, fund massive infrastructure efforts for rural areas, etc.
Why do we have such good and extensive roads in rural areas with such tiny tax bases? Because cities pay for it. Telephone services, electricity, broadband... all these are hugely expensive and inefficient in rural areas and need to be funded by the productivity of cities, which we gladly do.
Meanwhile rural areas have outsize weight in legislative bodies, and often make explicit laws banning cities from running in that they want to.

I can't think of any country (that has a rural area) where the statement wouldn't be true (although I could picture a counter example where the road infrastructure on specific rural areas is paid through export taxes and not city surplus, just none come immediately to mind).
That problem goes both ways and it is wrong headed whenever a single solution is imposed on the whole.
I've seen for example NY politics around transportation, where people that live in the city predominantly use public transport, but any attempt at traffic calming or providing more space for people "at the expense of cars" is an uphill battle because people from surrounding areas predominantly drive into the city. The irony being that following a "park and ride" model would make the city more appealing, including for those that must drive.
Having a bus coming every 5 to 10 minutes in some random place in Nebraska is never gonna happen, but not having that in a city like Seattle, San Francisco or even Los Angeles is ridiculous.
