Cool, thanks. I will do that! I'm in the process of releasing my entire mod kit, that I've been working on for a long time, and so adding more details will be part of that.
Just to answer the thing you mentioned: if you put a clicker remote in the car's equipment grid, and make sure it has enough power --internally it's just a battery, but it'll sever the remote connection if it runs out of juice -- , then click the scan button at the top of the clicker menu, that should add the car to the interface, giving a video of the car. Then you can click on the car's window to order it to do things like follow you (vehicles with tank-like driving work better than cars), for example: but I strongly suggest not doing this inside your base. :P And don't get run over! Hold shift and/or using left/right click does different things when you click on buttons -- I think the tooltips cover all of the options, but it might be cryptic.
As long as the remote unit has power, it will maintain the connection with the clicker screen. I don't think I'll be able to create an autopilot that can figure out how to avoid buildings (even the base unit ai doesn't do that), so using aircraft-type vehicles, like the dirigibles mod, and my and this other dude's hopefully-soon-to-come aircraft framework, will probably be best for the foreseeable future.
If you're not using the mod on a large multiplayer server, though, you're only seeing about half of the functionality. Because a big part of the mod is being able to track and pull up video on other players (all players as admin, or just players on your force as a regular player).
