It's way more than 300,000. Maybe people physically touching cars and car parts but there are thousands of small companies making very small parts like lighting, the handle for seat adjustments, the foam that goes into the seat, small plastic parts, and many more. Numbers I could find in a study made by the research group of the German parliament [1] were 800,000 and those are only people directly employed by manufacturers and their suppliers. 1: https://www.bundestag.de/resource/blob/496346/1a9b4fbe228b43b15bc6fbf3de0cb195/wd-5-122-16-pdf-data.pdf https://www.bundestag.de/resource/blob/496346/1a9b4fbe228b43...
