I’m not sure what you’re talking about. Public transport do run on the roads, too. It’s not “private car only”.
never said it’s private car only, but i did use wrong wording, sorry. what i meant was, those are the same roads public transport runs on, so the “cars can go anywhere” point kinda falls unless we’re talking offroading. mildly inconveniencing, but that’s just a tradeoff, it’s the entire point of fuckcars
The problem with public transport is that it only goes on pre-planned routes. If you want to go elsewhere, you can’t without a car. And replacing all nature with rails and asphalt is a very bad idea.
you don’t need to replace anything, the roads are already there. and if you wanna go somewhere super specific, just walk, keep in mind that if transport is more invested into, it will barely be different from car travel. the mild convenience created by cars isn’t worth the clutter that 10 times the volume of automobiles will create. also parking is already a problem now.
Taxis exist.
A quick search suggests that here in the UK the average driver is spending up to £200 per month on their car (excluding any financing to pay for it in the first place). That much money would easily cover a monthly travel pass in most cities I’ve lived in, with plenty left over to pay for taxi rides when you need the convenience of door-to-door travel at a time that suits you.
