Place a bot spawn above a vehicle, event it to give the bot the "wandering" movement type, and disable collision on the bot spawn. He'll drive it around.
Zone events. If you want I can post a quick example and instructions on how to do it if you do not understand what to do.
Found it!Just turn on the "vector" option on for the bot, and make him/the vehicle (I don't know, still have to test) where you want him to drive. You'll have to stop it with something like an invisible brick or a zone.
OH BOY!
a bot can't control the vehicle, although you can control the vehicle with events making it teleport or add velocity
a bot can control a vehicle, I've had one do it before
