For everyone convinced their Tesla does unexpected things regularly, I recommend investing in a GoPro or dashcam and mounting it so it takes in your driver inputs and the car's display. Power it from the USB port and put it into loop recording mode so that every time you drive your car it's recording you and the screen the whole time.
Then you can post up your video here when the Tesla decides to do something wacky and we'll all be able to analyse what happened.
I'm going to stick my neck out and say noone can post a video showing something which can't be explained by driver inputs. Go on, prove me wrong.
