Well, the point is to get rid of a lot of the traffic. And that's a good thing actually, with better air quality due to less pollution, more safety since there are fewer cars going around, which in turn helps with emergency services as it becomes easier for them to reach their destination, you get more incentives to use public transit, a bicycle or even walk places. Hell, for those times when you absolutely do need a car, lessening traffic makes that nicer as well, since you don't need to sit in traffic as much.
So yes, this propaganda is good for the environment and the planet, good for communities and good for individuals.
