How to shortcut like a cabbie
Higgins of "Taxi Talk" and Melissa Plaut, editor of the cabbie-themed newyorkhack.blogspot.com, recommend a few favorite routes to save time and hit the coveted sea of greens:
Shortcut One: If there's traffic on the way to JFK Airport, take the back route through Brooklyn (Bushwick to Pennsylvania to Atlantic to Conduit Avenue).
Shortcut Two: If the goal is to cruise uptown during the day, take 10th Avenue uptown for 40 or 50 blocks, which is better than grinding it out on Eighth Avenue.
Shortcut Three: If it's after 9 p.m. and you're commuting from the West Side to the Upper East Side, try 56th Street. The green lights are like ducks in a row.
