Musk took to Twitter (where else?) on Sunday to tease the next stage of Navigate on Autopilot's evolution. According to the tweet, Tesla is already working to add traffic lights, stop signs and roundabouts to the advanced driver aid. The goal, as Musk tweeted, is to automate as much of the commute as possible.
Like many of Musk's tweets, there are a lot of unanswered questions. We're not sure what the timeline is for this deployment -- heck, we're not even sure how far along this is. There's also the question of whether this kind of capability would need to be run past a regulatory authority (such as NHTSA) before being pushed to owners. It's also unclear if Tesla has tested these capabilities in the real world, or if most of its efforts have been on simulators.
Navigate on Autopilot seeks to take just a smidge more responsibility from the driver on the highway. It builds upon the standard Autopilot lane-holding system by adding suggestions for lane changes, in addition to navigation that extends to on-ramps and off-ramps., and we reported that the updated system completed its tasks "exceptionally."
Navigate on Autopilot isn't Tesla's sole focus for improving its suite of driver-assist systems. In late October,that Tesla's self-parking feature should be to "drive around a parking lot, find an empty spot, read signs to confirm it's valid [and] park" by 2019.
