Hughes doesn't believe a drop in the 12-volt rail voltage, as described in the petition, will cause a calibration error leading to an SUA event. The 12-volt rail is monitored by dozens of modules, which would log any low-voltage conditions. Hughes has personally analyzed logs resulting from SUA crashes and thinks a situation like the one described in Ronald Belt's petition is impossible. No log he examined suggests an associated 12-volt drop of any kind, and the NHHTSA had the same information when it decided to close the SUA investigation.

: 每次突然加速，都宣称是driver踩错了踏板。现在发现是inverter问题
: In a petition sent to the NHTSA, Ronald Belt claimed that the sudden unintended acceleration (SUA) cases reported by many owners were caused by a faulty inverter design. Since autoevolution broke the story, Tesla hackers have offered their own side of this story, and I believe you should read it
