Drove from Houston to Port Arthur/Corpus Christi for the Easter Weekend. Both coming and going, just after passing the City of Rosenberg on I59/I69 autopilot vanished the rest of the way to Port Aransas on what is a clearly true divided highway most of the time. When I drove back, the same thing happened, Autopilot just popped up as I entered Rosenberg on the way back to Houston. I used TACC most of the drive. Bit frustrating, but still a nice drive. When we drove on the freeways around Corpus Christi, AP2 resurfaced on parts of 35/37. Wonder if there is just not enough mapping data for AP2 to work that far 'south' in Texas even on true highways. Hope I added to the Tesla databank for future drives. AP2 was perfectly happy anytime my speed was below 35 on local roads and would show up and engage in it's usual slightly drunk fashion.
