Just a reminder that this thing is still not perfect. I was in the right hand lane on I-10 going east today between L.A. and San Bernardino. The freeway was "compressing" - the lane I was in gradually tapering to the left as the freeway lost one lane. Suddenly, for reasons unknown to me the car bleeped out the emergency warning alarm and flashed "take control immediately" - it lost its confidence on where the right hand lane marker was and began drifting over the line toward the right hand concrete barrier. The only thing I could think of was that there were some shadows making the right hand lane marker less distinct than it would have otherwise been, and this was a low-contrast section of freeway in general. However otherwise I am finding 8.0 the last couple days to be rock solid on relatively low-contrast freeway situations with poor lane markings. This is the first time in months that I've seen the "take control immediately" total autopilot failure happen.
