So how we can call what is behind the “ban this and that” mentality which is without any real study about the consequences and without any suggestion for alternatives ? Pre-intentional stupidity ?

Look, I am fully aware that what VW (and everyone else) did was a crime and I agree that they must pay. On the oher hand I also fully understand that you cannot change the reality only because you write a law to change it, in this case all the Euro-x normatives about emission levels.

Do you think that it is a silly idelogy to ask that also the people that make silly decision that they will not suffer are asked to pay for the consequences ? Fine, think this way.

Do we really lost the concept that one can agree with something but also see what the problems of that thing are ?

Yes, VW could have switched to hydrid or EV but not in the timeframe they are given.
Not to consider that switching the entire production to hybrid and EV without the necessary infrastructure to use them in the real world is useless, you simply build cars that nobody will buy.
