Again there is an innuendo that this is fundamental bad.
In my experience (having lived in London for decades), for most people who live within 5 minutes of a major train station, which is not most Londoners, it’s not even practical to have a car at all, and even if you do, just getting out of the city can take an hour.
London is great if you like urban environments and don’t like cars. But I don’t see why that should be a universally held preference.
