Some people want to drive it off the cliff.
Some people think we should push the other cars off the road.
Those folks are a few percent of us. Most of us want to use the car to get the kids to school, take care of the neccessities of life and an occasional vacation. We want to keep it well-tuned and running efficiently, making sure the tires and brakes are in good order. Where we differ is in which version of the owner's manual is correct.
