Has anyone else used Autosteer over Highway 17 (Los Gatos <-> Santa Cruz)? It was scary, but not for the reasons I assumed. There was a reasonable amount of traffic, so it had a car to follow the whole way, otherwise I think some of the curves and dividers might have been a little dicey... Instead, the scary part turned out to be when it read the "TRUCK - Speed Limit 35MPH" signs as if the speed limit for the Model X were 35mph (instead of the 55mph) and braked hard, then refused to go back up in speed until it saw a 55mph sign. Then it did it again at least one other time on the drive. Finally just disabled Autosteer. Very scary having the car brake in the middle of traffic for "no reason" since it mis-read a sign. First time I've seen it do this, has anyone else had any experience with this?
