Driving was a major part of my job when I lived in Boston and I drove manual. Honestly it isn't very fun being in traffic, but I wouldn't say it's much worse than driving an automatic. It becomes old hat. It probably depends a bit more on how stiff the clutch is and other mechanical variables, but I would agree with another commenter here that it does make people better drivers. I would also say manuals aren't for everybody and that's ok, but I also think they should be the norm rather than the complacently comforting automatics that make everyone feel like they are in a golf cart rather than a large metal missile.
