Add the ability to set if vehicles can collide (current default) or not with other vehicles. It should be possible to phase through other vehicles if configured.
Desirably it should possible to have multiple simultaneous groups like teams (but not teams) that could have different options. These settings should be adjustable at runtime so that it would be possible to assemble and dismantle such groups for different activities on the same creative map.
Note: This shouldn’t be just a general map setting. It’s desired to be able to register and unregister vehicles to and from multiple different groups, somewhat similar to how barrier devices now operate.
