Here's a summary of his entire background in order: Formula 1 engineer for many years; Technical director for a Le Mans Prototype vehicle; Head of VWs self driving division for the past 1 year.

He has no software background... he specializes in making gas cars go fast. He has no idea how to make a self driving car.. and honestly, why would we think he would? He hasn't exactly been pioneering vision systems, or anything else related to the tech.
