Criticism of Hummers: Hummers are significantly bigger than other SUVs; this can cause problems parking, driving and fitting in a garage. Even compared to other heavy passenger vehicles, Hummers without the alternate Duramax V8 engine have very poor fuel economy. Because of its weight, it takes longer and further to stop in emergency braking situations. The H1 lacks standard safety features, including child safety locks, child seat tethers, side air bags and stability control. Large blind spots make parking difficult and possibly dangerous. __
