Now that I live in Munich, doing folding scooter + train is faster than driving to work. Mostly because public transportation here is good, rather than bad, because they've chosen to invest seriously in multiple modes of transport, rather than just one.
I don't think most US cities would ever get to a point where public transport and bicycles are much faster for a lot of regular routes (like in some European cities), but the gap can be closed if there is political and financial support to improve the infrastructure.
I get that many jobs (and even more employers) require 8 hours attendance, that not everyone has volunteer work to do when they can’t work work on their commute, and that some public transport doesn’t accommodate any kind of being productive - but I’m still amazed at how many people prefer say 40 minutes driving to an hour sitting on a train and a 10 minute walk.
They are putting bike lanes on about 40% of my commute but 12 miles each way is a bit of a stretch.
A 12 mile winter commute in some of the northern states could be pretty dangerous.
