Saints Row 2 - Cruising with Homies

This is one way that I've found to be able to ride in the passenger seat of a vehicle while a npc drives.

This trick is easiest with a gang member who is already in a car. Walk up to the car and press up on the control pad to recruit the gangster in the car, once they are out of the car, walk up to the passenger side of the car, but don't get in yet. Hold up again and you will dismiss them, they should walk back to the car. Get into the passenger side of the car synchronized with the npc getting into the drivers seat. If done correctly you should now be in passenger seat of the car. You can recruit this gang member again now.

One problem with this trick is that when the npc sees a cop or another gang member fighting, they will get out and fight, forcing you to get out of the car.

Alternatively, you can call a "homie" on the cell phone, and then dissmis them, they should go back to their car, allowing you to perform the same trick written above, unfortunately sometimes they just walk away, leaving the car.

note that when riding with a character recruited through the cellphone, recruiting them again after getting in the car will make them get out of the car.
