I haven't been to many other subway systems in the US other than Chicago, Atlanta, and D.C. I would say in the US that D.C. seems to be the worst from the sense of long times between cars, full cars that stop but you can't get on because it's completely full, and making it difficult to add value to a stored value card. Including European systems I feel that I can tell if a system is good or not if it impedes the travel part of my day. Can I notice that the system is actively getting in my way?
