There's this great compilation video on youtube of Elon Musk promising fully autonomous cars "next year" since 2015. https://www.youtube.com/watch?v=o7oZ-AQszEI Sorry for the dumb clickbait title.
2014 - 90% capable of autopilot, for sure highway travel
2015 - autonomous driving for highways and relatively simple roads
2016 - S/X can drive autonomously with greater safety than a person - generally true, it still messes up for human-correctable situations but in general helps more than it hurts in terms of "crashes where autopilot was in control during impact or within 5 seconds of impact"[0]
2018 - incorrectly predicted - self driving will be 100-200% safer than a person by next year (this talking about their full self driving thing that will do turns and stop signs and whatnot)
