Driving a Hummer in Geneva

Today I saw a Hummer with CD plates - should I be pissed off on environmental grounds?

A Hummer uses goes 9 miles per gallon. My Nissan Almeira 42 miles per gallon. All of this rendered meaningless depending on how many flights a year I take.

A Hummer uses up loads of space on the road, pollutes way more than my Nissan and is a nightmare for cyclists and pedestrians. But then I guess the intern who I passed on the bus is probably saying the same about me.

OK, so I can't win the environmental arguments, but it does send out an uncomfortable ethical message if UN employees are buying these monster cars...
