Look, I'm not surprised by the chaotic failure mode. The Tesla I married into the use of tried to kill me last winter, near the end of a trip down the western slope of the Sierra Nevada, because the failure mode of its power supply overheating was to bring the car to 54mph and just...flash a picture of an orange turtle on the screen, with instructions telling me to get out of the car & back in to start it again. I am not making this up. I was doing 83mph on I-80 in Davis, CA. The car knew this.
