never ascribe to malice that which can be explained by incompetence...
I work at the French auto Inspection facility. I'm not keeping up with research done by some people in Brussels because I'm busy living my life. A car rolls in, I check for defeat devices of the kind previously found.
Because the organization is reactive, not proactive, I don't find any newer kind of defeat device (also, I'm not Sherlock Holmes). Car gets approved.
