well everyone knew the old tests werent valid yet it took many years
to get them changed

Valid in the manner they were tested. A real auto enthusiast knew they were
not real life accurate but they were consistent. If Brand A said 25 mpg and
brand B was rated at 30 mpg, you knew brand A was a realistic 21 mpg and the
other was a realistic 25. The trouble comes from the people that actually
believed the numbers and were disappointed when they could not achieve them.

A for getting them changed, it was a lose/win situation. Marketing would
lose because they could not brag about the high mileage cars they sold, but
the dealer would have to win with fewer complaints about not getting what
the sticker said they'd get.
