As a New Yorker: 40 minutes is roughly my boundary between "ordinary trip with no prior thought" and "I'll set aside a dedicated time and/or day to make this trip."
The city's bus lines are much more variable in service, and don't offer as many interborough routes.
Why would you go to subawaysheds.com to learn about taxicab stands? that would obviously be taxicabstands.com.
Why just NYC? Because does anything else exist outside of NYC? Maybe atlantic city, or the catskills, or niagra falls, but everything else is just unimportant
