Volkswagen had an opinion on that matter that has since changed. This was of course for internal combustion engines and the software modified the behavior of the car if it detected a smog test harness. In all seriousness though, if you modified something that reduced the safety of the vehicle and someone is harmed, I can only assume that would be a factor in the legal finding. I am not a lawyer however.
