The idea that this might have been a rogue effort by a couple of employees (or some oversight by management) is nonsense. The VW diesel cheat was a well planned software development effort, and as such it would have been accompanied by a project-management paper trail of titanic (or at least Teutonic) proportions.
Somewhere, on a VW server, is a source control system (e.g. Subversion) containing all the firmware code, the progress reports, the QA scripts, the bugs (in a system like JIRA or Bugzilla), the ECOs, validation reports, dyno test results, the entire history of the "emission check defeat" project, start to finish. Every check-in, every bug fix, every item would have been recorded, with names, dates, etc. The complete dossier would be gigabytes.
Which begs the question: Where are the whistleblowers? Where is the Edward Snowden of the VW case? Why has no car-company employee come forward? Is every VW employee so loyal, so willing to defend an obviously corrupt, immoral scheme, that no one will upload something to Wikileaks or speak privately to the press? How can workers be that loyal to a company that has clearly let its employees down?
Hopefully, no records have been destroyed. (That would add a new level of criminality.) In the meantime, VW's servers should be seized. That's where the smoke's coming from.
