First of all, wrong subforum. Second: If you mean that you want to make AI drive a route you've set, press F11 to open the world editor, then go to "window"... i think at least, then "gameplay", then "Script AI Manager." Open it and switch into the car that is supposed to drive. Then press the recording button and drive how you want the car do drive. When you are finished, you stop the recording, and if you click "more" you can disable that the route is shown and that if you play the thingy it doesn't loop. Now you can play that, and have the car drive how you want. The game records the steering inputs tho, not the position. Soo if you are driving a high HP RWD car really fast or drifting or shit like that, chances are AI will spin out, crash or something like that. my english is really braindead right now, sorry.
No problem, but i think you misunderstood the automation subforum here. Automation, with full Name Automation the Car Company Tycoon Game is a game where you can build cars. In 2018 or 2019 they partnered up with BeamNG and the game contains an exporter, making it possible to export the built vehicles to BeamNG. This subforum is dedicated to those exports. If you have another question, General Discussion and/or Troubleshooting: Bugs, Questions and Support are the subforums for this. And also welcome to the forums!
