Haven't seen discussion on this yet - but I'm just wondering if this is true. Here in Southern California I expect we have higher Model S density than any other city on the planet with perhaps the exception of the Bay area. Yet there are still certain conditions on I-10 and the 91 freeway which consistently flummox autopilot - low sun, high glare, faded lane markings and no cars around for the autopilot to help lock its position. I'm not saying the car wants to drive off the freeway but the wandering can get so bad I turn it off - not because I am scared (I'm more fascinated and want to see what it will do) but because I'm afraid I'm frightening the cars behind me, perhaps so much that someone will call 911 and my plates in and tell the cops I'm drunk. If these high definition maps Tesla claims the fleet is building, and the vaunted fleet learning are both in fact actually working - I would have expected that the Los Angeles freeways would be almost 100% bug free by now, even in the glare conditions - because in theory the fleet of local Teslas should have mapped out all the lanes by now. For those of you who do not visit So Cal frequently, Teslas seem to be everywhere - even 80 miles east of Santa Monica all the way out in Riverside and San Bernardino. Also remember how Elon told the world that Autopilot was delayed in the final months leading up to 7.0 because Tesla was trying to improve reliability in the "corner cases" of poorly marked sections of the 405. Clearly the problem is not completely solved yet 6 months later despite thousands of local Model S's tracing the same routes day after day on our freeways. Thoughts?
