I'm both excited and skeptical. There was a similar demo in 2016 and then repeated claims that full self driving ("coast to coast with no interventions") was less than a year away. How is this different? Apparently people at the event were taken on demo rides and it was very impressive. However, Tesla's current system has several notable issues like crashing into stationary vehicles at highway speeds. So what's the truth here? Very exciting if this is the breakthrough we've been waiting for, but I'm skeptical of all claims until released into the wild and shown to be generally true.
