I hate the underground. When I lived in London, I travelled by London cab mostly or bus - or often walked. I just hate being enclosed underground with crowds of people.
I don't like the NY Subway, but the London Underground was fine, IMO. Unlike the NY Subway, it was clean, and I didn't have to be ready to punch some low-life in the face.
We actually have a pretty decent light rail system in Dallas. There has been a plan for a high-speed rail system between Dallas a Houston for 20-plus years, but conservatives in the State legislature keep blocking the funding. Seems that public transportation is "communism" in Texas politics. "That don't burn enough oil."
