No it's not. Not by far. That's just to get cars out of already existing dense urban areas because as long as you take aboveground space for parking cars, you can't plant trees there, and massive amounts of cars in relatively small spaces produce really nasty local emission concentrations.

Suburbs can be perfectly well served by buses, connecting to train stations that in turn connect to larger agglomerations. The idea is to have a dense enough mesh so that almost no one needs a car for their day-to-day individual transportation needs. Employment-related transportation (such as farmers, tradespeople and the likes) is obviously going to need dedicated vehicles even in the future, but the primary goal is to get the 80% [1] of individual transport made using cars down to as close to 0 as possible because that's where the masses are made.

Denser housing is a prerequisite for this?
