Non Functional Vehicles

Is there a way to incorporate vehicles into a map and have them not work? I saw a disable vehicles setting and tried it but the vehicles still drive and weapons fire.

Two options.

Globally set that players cannot drive vehicles in game settings.
or
Have vehicles explode in the air and land where you want it to.

The problem I was having was finding where to set the options. Actually, I did find them before I had posted this question but for some reason I failed to set them correctly. I got it worked out now. However, I like the idea of having a blown up vehicle or two on the map, great suggestion. Thanks.
