Note that we hardly have poor people (by American standards) because of the welfare state, which is partly funded by these extremely high taxes, but it is difficult for low income people to afford a car (gasoline is heavily taxed too). If they really need it they will buy an old beater and drive it a couple of years until it dies, then repeat (which somewhat nullifies the rationale of car registration fees helping the environment).
