You need to have 50-50 car engineers and software engineers and they need to work together to make that move happen. Do you think a guy with a black Star Wars t-shirt and an Arch Linux running Thinkpad could get any meaningful say in product development at any big German company, car companies and banks especially? If you would answer that with "no" we basically have the same view on how the German industry looks like. What we may not agree on is if that can succeed any longer in the automobile market.

German car companies and their suppliers (Continental, Bosch, ...) have already lots of smart engineers in this domain. Their current factories are among the highest automated in the world. Volkswagen invested $15.3 billion in R&D last year, Daimler $7.6 billion, BMW $5.5 billion. Number one, three and seven in the automotive world.
Tesla was spending $0.7 billion for R&D in 2015.
