Anecdotal evidence— we have a good family friend in Montgomery county, and she moved to an apartment/condo, which is convenient to Metro.
But the Metro subway has had so many problems, that she now drives to work instead most of the time.
So even people who try to structure their lives so they can use mass transit, sometimes give up.on it.
Metro, unfortunately, spent several decades not keeping up on maintenance, so now they’re paying for it big-time.
When I used it regularly in the 1990s, and fairly often in the 00’s, it was a first class system, but all the crap and negligence caught up to it, so it’s now a miserable thing to use.
