Ford has been doing a good job with some of its recent seat designs such as those in the Freestyle SUV and Five Hundred sedan. But the new Ranger head restraint is more than three inches below the top of the head of an average-size man. This means it won't begin to provide adequate protection for many taller people in rear-end crashes. It's puzzling why Ford decided that buyers of the new Ranger should get less protection against whiplash than people in some of its other vehicles. Adrian Lund
