Not long ago I was driving with a friend through the English countryside. The car had power to speed along the roads, and was plenty nimble to take corners well. Then I asked my friend: “Does it bother you that your car is a Volkswagen with a diesel engine?”

I was expecting remorse, if not anger, at being duped by VW. Instead the response was: “Other automobile manufacturers have caused problems, including General Motors and Toyota, and their transgressions caused loss of life.” Other VW owners have said they don’t want emissions systems fixed if it will affect performance.
