Yeah, this is 100% false.
I've owned a Tesla for over a year.
I take several curves on a daily basis with the speed set to around 82 mph. Going into the curve, the car slows down to about 65 mph, which is the speed every other car on the road takes that curve. It's even stated in the AP documentation and release notes. Go ask other Tesla owners as well. I've never heard of a Tesla being "swung" out of a lane on a curve.
Tesla uses a combination of the visual lanes, cars in front, and an accelerometer, to determine the curve and how much it needs to slow down.
Other than a freak situation last year (not on a curve, it was the hill crest with the white truck crossing the highway), every SINGLE accident has been shown to be the drivers fault with autopilot disengaged. Not a single accident of what you described has happened.
You may however be overestimating how much a car like the S needs to slow down in a turn. It has a really low center of gravity. Maybe it didn't need to slow down at all and you were just being paranoid.
Can you provide a map link to the stretch of road where this happened?
I don't think I was being paranoid....I'm generally a very, very fast driver who prefers the inner lane and 85mph+ speeds given the opportunity. I do know the car has amazing handling but it unequivocally started swerving heavily out of the lane at the speed it was traveling at.
It's route 90 between Allston and Back Bay. It looks like a pretty gentle curve so looking at the map certainly makes my description of events seem questionable, but I can only tell you that it occurred as I described.
