I posted this in another smaller thread, but wanted to see if anyone else is seeing this behaviour. Let me know if it isn't clear.
One MUST have their hands on the wheel at all times, ready to take over in an instant when FSD decides for whatever reason to DIS-ENGAGE steering control and hand it back to the driver. I have two locations where after either making the beginning of a turn or simply turning IN A curve at speed 25-30 miles per hour, FSD steering control will disengage and if my hands aren't on the wheel at the time the car would just drive into the side of the curbed curve or off the road at speed. IMO this is a totally unacceptable result but if I only had one hand loosely on the wheel and wasn't ready for this type of crazy return of control to the driver with no advance warning, could prove catestrophic.
I should add, I can reproduce this behavior in the same curve each time, this is three times now. It's so predictable that my frequent passenger now reminds me (as If i would forget about it) as we come up to this curve and I tell her I'm just trying to test if it's learned anything, if it's interpreting the data differently because of TOD or other vehicles, but sure enough it disengages and I have to instantly take control to keep it curving on the road. Sad.
