xsboy told his father after our Sat AM jaunt in manhattan that he didn’t think that driving in NYC was any tougher than driving in DC. on a SAT AM, maybe not.
Both my sons went to school in D.C. and I spent many Saturdays there. I think Washington is tougher because the streets are laid out like the spokes on a bicycle wheel, whereas NYC is a perfect grid, with streets running east-west and avenues running north-south.
Of course, NY cab drivers are justifiably famous for their aggressiveness, which adds a bit to the difficulty. Whenever I visit the Big Apple, I take off my polite, suburban, "sure--you can squeeze in ahead of me" manners and go into Earnhardt mode. The cabbies can sense fear and weakness!
