> Taking measurements on the "12V" line and seeing voltage dips as low as 2V. Watching this voltage-dip propagate over to the 1.65V reference voltage used by the TI and STM32 chips's ADC.

Did we read the same paper? He takes no measurements, everything is based on theoretical assumptions, schematics and the three youtube videos he mentions in the beginning of the paper.

From the paper:

> The enclosed paper proposes a simple test that can be done to prove or disprove the explanation provided. This test has not been done by the author because of the cost involved with acquiring the needed Tesla Model 3 inverter PWB.

> The details of Tesla's Model 3 inverter design as revealed by Irish engineer Damien Maguire have been presented. These details were used to construct *a hypothetical model* of all hardware and software operations performed on the two accelerator position sensor (APP) sensor signals inside the inverter as they pass from the APP sensor to the electric motor controller.

He doesn't have access to the parts in question nor the car in question.

Also of interest is the authors own comments on his previous papers about sudden unintended acceleration:
