Best and worst transportation infrastructure systems (cities) in America?

Based on public transport I have to give the nod to DC as the best. The system has good coverage, doesn't seem all that prone to delays, seems clean, and has never given me any problems on bus or subway. Honorable mention to NYC, if the MTA wasn't so prone to delays every day it could've gotten the top spot. Based on roads, I have to say Memphis. Despite a large population and pitiful relative public transport it seemingly has very low traffic.

Huh, DC is good? I keep hearing that the DC Metro is one of the worst in the country. Are you referring to the non-subway aspects?

And going off of that question, which city has the best transportation infrastructure worldwide?
