The Hummer H1 is 86 inches wide (by comparison, a Ford F150 full-size pickup at 79 inches wide, and a Ford Taurus is 73 inches wide). It gets 10 miles to the gallon. It costs $105,000. As a Class 3 truck, it does not have to meet safety requirements for smaller vehicles (for instance, it has no airbags).
A man in his 20s or 30s was driving the Hummer. He was alone. I could see no cargo in it.
He did wave thanks at me for waiting for him to back out of the parking spot.
