Overall, I think its probably necessary. But, as a relatively un-wealthy person, it makes me nervous. When businesses know they can charge more for something, they do. And that makes it unobtainable for many less than rich people.
I'm glad to see they're working on the infrastructure as well. That's a huge problem here. For a lot of portions of the country, a car isn't a luxury, its a necessity. Many cities aren't set up for pedestrians and bikers. We have a lot of work to do if we're going to make this place more environmentally friendly. Its a move in the right direction, but we have to make sure we're examining the whole situation to make this workable for all.
