Columnists | 40 mpg claims grab headlines, miss mark | The Detroit News thanks to http://www.thetruthaboutcars.com/20...oes-anyone-actually-get-40-mpg-on-the-highway. Too bad detnews.com blocks archive.org via robots.txt. Detnews articles get aged off... As I've mentioned before, this is one of my biggest pet peeves of car advertising. If it were up to me, it would be illegal to advertise only the highest figure from EPA estimates. They ought to only be allowed to do one of these: - advertise combined mileage - advertise all three figures: city/highway, combined w/equal prominence. None of the current shenanigans where only the highway # is mentioned aloud or the highway # is in a large font while the other numbers (if present at all) are in a tiny font at the bottom of the ad.
