I was using Autopilot today for about 15-20 min when I suddenly got the alert that autosteer was unavailable and I was forced to take over. Has this happened to anyone else? Luckily it occurred when the car was going fairly straight. If autopilot had shutdown during a curve section of the freeway I might not have reacted in time. Really dangerous to be honest. Not sure why it did this. I couldn’t activate it again until my trip home. I didn’t ignore any nags to keep your hand on the wheel or anything.
