> UK average is about that.
Yes, and the average UK person is driving more than they would if there was better public transportation availability.
Sure, not every household is going to be well served by public transportation, especially in very rural settings, but way more rural areas can be well served by public transport than they currently are.
If you think you need to live in London, Paris, or NYC to have good public transit, you're simply wrong. There's lots of rather rural places that actually do have quite good trains and bus options.
There'll still be lots of people for whom a car makes the most sense, but we can still strive to reduce that by giving more options and building better infrastructure.
