The Silver Line was built to serve the single largest commuter destination in all of Virginia. At that scale, rail transit is cost effective. Rail transit wouldn't make sense for a smaller scale development like the one described in the article. At this scale, dedicated bus lanes would make more sense and would be much, much cheaper than rail.
> One of the significant reasons we started moving away from this kind of development, even before cars became common, is that it traps people inside of them and prevents people from getting into and out of them.
This kind of development is constrained to really make car ownership a reasonable thing (I know I know, he has photos of 3 or 4 cars in some of his examples). So getting into and out of this kind small scale development requires something like rail for interconnections -- I agree buses or trams would be better for intraconnections.
