I’m having a significant safety problem with the auto steer on my Model S 2017 build, Software Version 50.6. AP2. While driving on the Florida Turnpike at 75 mph, I engage the auto steer program. The road is very straight for many miles. The auto steer started with small variations in tracking while keeping a straight line. The variations increased to swaying back and forth side-to-side with the deviations increasing. I had to stop before the variations became a safety issue. I’m sure I’m not the only owner having an autosteer problem. What have been the responses from Tesla and what are the cures for the problem ?
