Your post reminds me of the unintended acceleration controversy with the Audi 5000 about 35 years ago. They did find that a device in the throttle mechanism could open the throttle by some amount if it became defective (and a small number were found to be when they looked). But the “60 Minutes” program modified an Audi to reliably malfunction and showed the result in a broadcast as “confirmation” the car was defective. Audi sales dropped partly due to that broadcast. Wasn’t a good day for the truth or the reputation of CBS.
