It's modeled on GTA, but I usually reference Crackdown or Just Cause because those are open world games I've played a lot.
I really got into the transit system and helicopters late in the game. You can just jump on a bus and follow it's route, or have a taxi or limo follow your own route. I did that all the time to travel the city, just for fun. You can fast travel via subway whenever you want too.
