Unfortunately, my youtube abilities do not extend beyond screencaps atm, but the steps are fairly simple:
1. First I have to assume that you have a project with a functioning character object. I used Chebob's Advanced Mouse Control
http://www.3drad.com/forum/index.php?topic=3605.02. Add a vehicle to your project, and attach an EventOnLocation to the vehicle (make sure you set the vehicle as the parent to the EOL)
3. Add a Chase Cam to the project, and set it to follow the vehicle.
4. Add the Above script, then set the relationships as needed, and adjust the OBJ_XX's as necessary to match the commented section.
Poof! You are done...
BTW there seems to be an issue with switching between cameras, so I strongly recommend using some sort of script to control the camera...Chebob's script above works amazingly well... check my youtube vid above to see it in action...
