Why would you assume it would be hostile? Ultimately either someone's going to buy Tesla, or Tesla's going to buy a legacy automaker that's in trouble. Setting aside dealership issues in the US, it doesn't make sense to rebuild an entire worldwide distribution system from scratch when the innovation is the car, primarily. Either that, or license the Tesla tech to a major car manufacturer and let them serve the downmarket while protecting the Tesla brand as high-end and innovative. I don't think Tesla wants to become Honda.
