Skycar

The Sky Car is a aerial tram that connects Algonquin to Colony Island in Grand Theft Auto IV, just south of the Algonquin Bridge. Niko can take a ride on the Sky Car, though the player cannot see anything or do anything. First person view can be accessed through the Cell Phone, once it is upgraded and has camera capabilities. It is possible for Niko to hold onto the sky tram in the station, but once it takes off, he just lets go.

The tram is evidently based on the Roosevelt Island Tramway.
