EDIT: This PDF contains very detailed electrical information for the EEs who wanna go through the complaint: https://www.autoevolution.com/pdf/news_attachements/breaking-nhtsa-petition-shows-tesla-s-sudden-unintended-acceleration-is-real-and-curable-217525.pdf

Last year at /r/RealTesla, a Chinese video of a car rocketing at full speed for 1+ minutes before crashing / killing a pedestrian made the rounds. We all recognized it as one of the weirder cases of "Sudden Unintended Acceleration", and I think that particular video really changed some minds.

While a lot of SUA events are from driver-error, it began a search into why Teslas seemed to be getting more SUA above-and-beyond the industry normal. This investigation (now filed under NHTSA) suggests that the ADC could be miscalibrated during a load-dump (or other electrical surge-like) scenario.

If the ADC associated with the accelerator pedal is off, then the Tesla will have the pedal at the wrong level of acceleration until the next calibration event, which is not going to happen until over a minute later.

This is extremely similar to that Chinese runaway Tesla, and perfectly seems to explain it. I'm glad that someone seems to have gotten to the bottom of this.

I do think that Democrats turn their brains off if you say its "Green Technology". But this is an obvious safety issue, and historically Democrats are more for keeping ya know... regulators actually regulating?

Republicans have a point about when regulations go too far and hamper innovation / etc. etc. But this safety issue got through Chao and her department in 2019 and 2020. That's fully on them for making NHTSA incompetent in the time of need.
