How do you get people to follow you on vice city?

First step is to get a car, basically any car will do, except that prostitutes actually don't get into your car if you are driving a sports car. So with your hooptie in hand, ride around any neighbourhood at night and you'll usually see scores of hookers trotting around. Pull up to them and honk your horn. They'll usually saunteer over to your ride and stand there for a little while before getting into your car. Then just drive to a remote spot and start tearing that booty up! A few good spots include the bushes in the middle of the road new the restaurant at the edge of Little Havana, across the street from the Police Precint.

Also it is possible to get two hookers into your car at the same time.
