Fairness is a requirement. 'Liberty and justice for all'.
Nobody is saying to give it to them. But fairness is that they have equal access to the roads. The idea that wealthy people have more access to public roads is really an abomination in the US.
You're free to suggest public transit, but they need to be free to make their own choices, completely disregarding what you - incredibly - think they should do.
The fact that it's not achieved in some ways makes it more important that it's delivered in others, and for us to stand up for it.
Only in a libertarian fantasy where you only deserve, as a human being, what you personally pay for - even access to public roads! Should the wealthy have privileged access to everything? What about those wealthy people who pay no taxes?
We all are subsidized very heavily by our ancestors - consider the difference between a barren country devoid of all development and what you were born into. And more importantly, what humans have a right to, what is moral, etc. does not depend on money. Fairness isn't generally or primarily dependent on how much people spend.
Roads are public goods, built by everyone for everyone.
