Driving around in LA and I can tell you I am not surprised. I had 3 interventions on left and right turns today that would have resulted in accidents if cars were around. Right turns where there is bike lane is a problem, AP gets confused. Turning onto a street just after a train track crossing almost resulted in turning onto the track. And going down a street with cars parked on both sides with oncoming traffic almost resulted in a side swipe. This is alpha. I hope the snapshots are helping. My current setting is now chill mode, with speed set to -5mph of the speed limit. I rather manually increase the speed as I don’t trust it. AP forces you to be more attentive and is stressful. Bright spots are there too. Generally good at 4 way stops, going to try round-about tomorrow, left hand turns are better than expected. It sucks at turning on a grade, usually need to take it at an angle or it will scrape the bottom. Lastly it cannot see a folding barricade with yellow reflective light, tried to turn left directly into it.
I think it’s going to take a long time for this to be safe for general release. I don’t see it happening anytime soon, there is just too many variances in street markings and signage. Tesla should start working on lobbying for policies to standardize street markings/signage for the benefit of all AP systems. We are many years away from this being street safe IMHO.
