Every automated car I’ve driven behaves like this. I don’t buy it’s a calibration issue (there’s nothing to calibrate from what I’ve read on wiring diagrams, as that’s not how auto manufacturers roll - they build components for things like this to be replaced).
For example, I haven’t heard of headlight aiming in forever, though it’s something that used to be done with a relatively simple tool. And it’s way simpler to do than calibrate a complex radar system for a car.
This automation simply isn’t quite ready for the real world, and I’d bet manufacturers are collecting data from many of these cars (so many have a connection back to the manufacturer via cell).
