Where I am in the US, I just have to drive or die. Easy access to public transportation would be such a godsend here.
I've been through England, France, Italy, Japan, and Korea and it seems the public transportation is just so much better everywhere else.
I would gladly give up my car, the commute, and traffic in my old age to get to the city center easier using an exchange or ID system or whatever.
Kudos to you abroad.
