Kei cars are very inpracticle for long distance driving.
practical as second cars, and thirty years ago families used to go long distance in Escorts which were the size of current Fiestas.
I know several people who live in a tower block and own cars.
I am not sure you, like many posters here, understand the pressures of real people. You and others have no practical solutions for the modern world. You seem to want to decide who may own a car based on their social stays. Live in a terraced house? You may not have a car.
Perhaps we could sign up for a car and have one assigned in 7 years. Hang on, they tried that in East Germany......................
Am I not a real person? A person who chose a smaller home so I could live fairly near town and still have a parking space - compromise. Terraced housing can have cars, but they might not all be allowed one, certainly not two, or they may need to be smaller.
If you live somewhere sparsely populated then there should be space to provide parking, though it may not be right outside your house.Being in one of the more sparsely populated regions I'm very strongly opposed to the notion that people should have to move out to large towns and cities to find work. That can be disastrous for communities. Incidentally, the workplace I mentioned is where it is due to UK and EU grants, it is in a rural location by design, not accident!
