You know, I see these "discussions" started at times that seem to be looking for debate/discussion, but from all I've read from past ones (and it's no different in this one) don't think I'd ever care to try to express my opinions because any disagreement ends up with personal slams and plenty of use of Yes I've seen it go on between both sides of an issue. Personally if I see someone asking for a serious issue to be discussed, my thoughts and replies on it are serious. Some people use and and "LOL" so frequently that it's not always a clear indicator of intent. Just food for thought.

As an aside, from what I have read, the US has one of the worst overall mass transit systems of any of the 1st world countries. The big cities such as NY and Chicago have them for within their boundaries, but in many places it is sorely lacking.
