SUVs are status-mobiles for most people. I know some people who have them for logical reasons (they do have a large dog that rides in the back on a regular basis, do a lot of moving of stuff for girl scouts, etc.), but most it is the show off factor.

The fact that you can see better from one (who cares if it means that the REST of the drivers on the road can't see anything) is probably a bit of a selling point. Esp. since you are higher and that leads to a feeling of superiority.s
