I worry more about tight turns when going up hill. There are 2 places in NYC where I have problems with that, the entrance to the GWB on the NYC side, and the climb from the west side trail after the lighthouse, also under the GWB. The one on the entrance is made even harder by the a-holes that want to blast up and down the ramp as if they're in a cat-2 race. This ramp is shared by bikes and peds and can barely allow two bikes to pass.
