It's nice to see some governments recognizing that something which was once a luxury is now becoming a necessity as offline alternative for mandatory services (paying bills, job searching, etc) get stripped down or removed entirely.
A car used to be a luxury, now it's a necessity. Do you think owning a car is a legal right?
I live in Portland, so I'm questioning your premise off the bat. :) I'd say freedom of movement and the ability to reasonably exercise that freedom is the right, which governments legally support by creating/maintaining/policing the roads.
