Really? Why wouldn't it make sense? Tesla helps VW make EV's and VW invests a few billion into battery factories that will be shared with Tesla. Why wouldn't this make sense? Force VW to invest $20 billion in EV's as punishment for lying about emissions. Makes complete sense.
Why would the German government select Tesla, specifically and exclusively, to "force" VW to collaborate with on remediation? Also, the German government has no jurisdiction over Tesla to get/force them to help VW. While it may make sense to us, it would never happen unless other companies were also involved and it was a deal to good to refuse for Tesla.
