The last time I read any updates on this, everyone on both sides of the legal process were trying to single out scapegoat individual software engineers and rake them over the coals. Did something change?
I don't think software engineers were independently looking at emissions data and unilaterally decided to "fix" the emissions shortcomings in software. I think they were told by others to do that. It's good that Germany is going after the people who decided that fraud was the answer.
When the VW scandal broke, the US indicted seven senior executives. None of these seven were extradited to the US to stand trial [1].
The VW scandal was made public in 2015 [2] and involved cheating since 2009. Sentencing only two executives to jail a decade after their wrong doing made international news does not send a strong message.
