Hostesss may have done that on purpose to save brake wear. That may have been a good idea when fuel was $1/gallon, but not so hot these days.

Look into having someone change your top gear for a highway gear. If you get the engine RPMs down 25% that's a 25% improvement in fuel economy (I think). You may be able to tell what your drive gear is by a plate on your transmission, or on the options list sticker if it's still there. Or it's possible to calculate the gear ratio by knowing speed (true speed, not speedometer speed), engine RPM and tire diameter.
