I was in full "Russian Roulette Suicide Mode" today. This is about as far as I have been willing to go before disengaging for a stopped car that Autopilot seems completely oblivious to. Still can't figure out why it does this only once in a while. In this clip my Tesla Model S 90D is in Autopilot barreling down the road at 57 mph with no hint of stopping. I didn't disengage by applying the brakes until I reached the left turn lane of the intersection. Firmware 2017.50.3 f3425a1.
