Even if you already own a car, it is in general more expensive, inconvenient and maybe even slower to choose to drive to work. As a general rule of thumb, driving long distances costs about the same as taking the shinkansen for one person, is slower and makes more sense once you have 3+ people in the car.

I think overall this is fair and leads to much better outcomes than US-style "it's my right to drive and park for free where ever I go, but I will fight any proposal to improve or subsidize transit because 'my taxes!'".
