Are our Slants "Unsafe"?

What are people thoughts on vehicles that have intentionally been made more dangerous to other people? You prolly don't know what I mean. Ever see a lifted truck. What happens to a car's crashworthy (regardless of designed in safety) when instead of taking the impact at legislated bumper height the car gets hit at the top of the window frame?

I would like to see some crash tests of new and recently used (2000-2005) cars where the side impact ram is 4 off of the ground at its lowest point. Same test scenario, same test ram just raise it up and let her fly. I bet even some of the 5 star safe side impact cars would look a little less safe.
