...but I cant find an answer to. We currently have an AP1 2015 Model S with AP1 autopilot, which is enough for me. AP1 will turn on autosteer on any road it can pick up lane markings on; highway, back road, long driveway, whatever. We are looking to add to the pack and get something 2016 or newer but I can't find an answer as to whether or not 2016+ "Autopilot" (as described on the vehicle descriptions on the used tesla site) will operate off highway like AP1 does. My Tesla salesman doesn't even seem to know the answer. If base "Autopilot" on ap2+ cars does not work on back roads I need to get EAP or FSD because I use it on back roads a ton. Thanks in advance...
