Even in cities, transport is only good for some things
I live in North London, on the edge. Transport is amazing going in and out of Central London. If you want to travel east or west a few miles you need buses
Buses are great when you’re stopping on a particular route, but if you’re not then changing buses is a PITA
We’re going down to 1 car very soon as we don’t need 2. I ride most places locally, plus I have a motorbike. Car is needed for day to day stuff like seeing family, stuff with the kids etc.
To be fair if we didn’t have a car we probably wouldn’t do a lot of that stuff, and change what we do. But having no car at all would be a real pain.
(I personally don’t really like buses, but I can cycle to most places so I’m generally fine)
