No Problems at all!
This is by far the most comfortable vehicle I've ever driven, including Escalades, Tahoe's, Coupe De Villes, MB G Wagons... You name it!
And the way people drive today, I have to take care of ME, So I feel the gas mileage 13.5 MPG is not bad at all as long as I am safe!! At least I'm buying American!!
So, the Hummer is the only way to feel safe?! What kind of terrains are you driving on, minefields?
Why don't you learn how to drive instead of buying an oversized vehicle to compensate for your lack of ability. I find a small good handling car with all wheel drive is much safer than any Hummer because I can avoid getting in accidents. With the Hummer you will just plow through anyone that gets in your way because it reacts too slowly to sudden maneuvers. Safe for you... but disasterous for them. It is sad that the mentality of so many people is to be selfish no matter what the cost may be to the other accident victim(s).
