VW ... by cheating they have killed people.
Really? I think we need to see one evidence of that.
You never were the sharpest tool in the box, were you!
Right, so actually you are bullshitting. You don't know.
The questions you need to answer are
1. Exactly which emissions does this cheat device suppress?
2. How much worse are they in real driving?
3. What percentage of the total emissions of the type that is the answer to Q1 by all vehicles does the answer to Q2 represent?
4. How many extra people are dead as a result?
I don't think you know the answer to any of those questions (well, maybe you know Q1).
