>>>People love to respond that that's too expensive or unworkable or unrealistic or whatever, ignoring that it's actually the status quo that is too expensive, unworkable and unrealisitc

I'd want to see some numbers to support that. What does it cost to provide round-the-clock availability of secure, climate-controlled public transport to every possible location, urban or rural? Bullet trains on standby at 0100hrs to take 1 guy from Osaka to Kanagawa would cost a fortune. In comparison, while PARKING and roads definitely have costs associated with them, the hardware/infrastructure is largely concrete, and inexpensive to maintain when operating below capacity. So 1-2 people can hop in a car and take a road trip at a far lower net/civilization-wide resource expenditure.

Japan has great public transport. Japan also has great cars and a very healthy car community. What part of Japan's transportation approach classifies it as "unworkable and unrealistic" to such an extent that completely banning cars is the optimal solution?
