Some cities have quite nice and convenient public transit, and it can be even better if you live and work in the right places.
Yes, and they're all outside the United States. :-)
Really? I live in NJ, and work in Manhattan. My monthly PATH card costs $89; that $4.45/day, and my monthly MTA MetroCard costs $112; that's $5.60/day. I've a 5 minute walk to the PATH each day ad a 5 minute walk from the subway to my office. So for $5.02 a trip, I get from home to work on the (mostly) reliable PATH and the (somewhat more reliable) NY subway in an average time of 20 min (best is 15 min; worst was an hour).
The PATH is almost always clean (if a little packed in the mornings); the subway is the E line, which originates at WTC so the cars are cleaned and not so packed.
All in all, for my daily trip cost it's a pretty good service.
The alternatives are a taxi (good luck with getting one to cross from NJ to NY or the other way) or a car service. The times I've had to use a car service it was a $50 "mate's rates" fare one way, and took 30-40 min, thanks to the traffic in the Holland tunnel.
However, if there's an Uber or Lyft service that offers a one-way service from NJ to NY, can get me there in 15 minutes or less and costs less than five bucks, I'm game to try.
