It would be cool if Beamng had more advanced electrics/driver assistance systems. I know there are already mods that add things like backup cameras and AEB, but I think having those things built into Beamng would be cool. I also think having those systems based on actual sensors would be neet, like having a camera mounted behind the mirror that, if damaged, would cause the AEB/lane keep system to no longer function and throw an error message on the dashboard. I know this is probably something that would be ridiculously hard to implement, but I figured I would just throw it out there.
