I lived for 3.5 years in the Arlington area, and would tend to suggest that mass transit appreciation peaked out around a decade ago.
I would go and suggest that anything that has to do with using more buses, won’t be getting much support from the public. If they’d go and add either more Metro routes into DC, or perhaps just add three or four monorail-type routes from 20 miles out (say large parking lots in the middle of these urban zones) and get you into DC within eight minutes....it would draw more public support.
I worked with one guy who simply gave up. He moved his family about 200 miles away, into better living conditions, and he had a RV camper that he kept in the local area...going back home every weekend.
The biggest problem in many of these metro areas is that it’s almost impossible to serve a suburb-to-suburb commuter market with mass transit. You’re witnessing a harsh reality check for modern American suburbs.
