I cannot read the fiery letters, but it’s quite possible, depending on how the affected metro vs the voting block overlaps, that those who vote aren’t those complaining.
Also complaining is easy, I could do it right now here on HN from any bathroom in the world; voting is comparatively much harder.
I've noticed in my city that a lot of the complaining about impinging upon the car-centric status quo comes from people who live outside the city.
