It's not sarcasm, I'm just very surprised that everyone's opinion is so one-sided about this.
I think if you put yourself in the engineer's position, he probably didn't believe that having a switch that was a bit easier to turn would lead to anything more than mild inconvenience.
I think if GM honestly thought this would cause even one death they would have changed the lock barrels. Even if you ignore the human side, the potential costs damages from something like this would totally outweigh the cost of changing them.
