No, no, and no. Cars are getting more and more efficient, and there are many affordable efficient cars today. It‘s just that people in rich countries like to display their wealth by getting a big car. But there are still people that live in the countryside, who have no other means of transportation, that‘d get hit pretty hard by even higher taxes on fuel. It‘s how they get to work, how they get their groceries, how they get to their friends‘ place.
It‘s easy to renounce something if you‘re not dependent on it.

What part of the population exactly are you referring to? Low-income households? Tax evaders?
