Just wait (I'm afraid...). The problem is that this could be a huge scandal throughout the car industry and similar to Syrian (or Egypt), you need to be careful what you wish for. If this scandal makes the rounds, it could really harm the whole car industry in a very very bad way. Not sure it is worth it because of some numbers, just saying. Yes, laws are laws but if tens of thousands lose their jobs, I don't know...
Therein lies the crux of the problem: How do you penalize companies violating the law, egregiously, to the point where it doesn't pay as a business decision to do it, without putting them out of business and, as a consequence, thousands of workers out of jobs. I think the only way you can do this is to make such intentional violations criminal offenses. So, in addition to a painful, but not destructive, fine, the persons responsible, at the top of the organization (not the engineers who were ordered to implement it) go to jail for substantial felony terms. The company goes on with new leadership, the workers keep their jobs, and the CEO has a few years to reflect on his bad behavior and make license plates, while getting a few tats and becoming someone's bitch.
If there is an expectation that you can get away with "acceptable" fines, relative to profits gained, it becomes simply a business decision to break the law -- i.e., crime pays. Put those same executives in a position where, in addition, they personally may face serious prison time for the same decision, and they are likely to be much less inclined to take the risk.
