When you say "most" remember the fact that DSMs are not "most" cars. I was unaware that DSMs will not push that ragged edge, but I can assure you that "most" cars do in fact run like this. Granted DSMs are a different breed seeing as they are turbo-charged. But, cars equipped with knock sensors do in fact push the limit in the name of gas mileage.
