About the only thing I remember from high school physics (which I took before many of you reading this were born) is that when a VW bug (original version) hits a Cadillac head on, both doing 60 mph, the Cadillac slows down to 30 mph. Yes, that means the VW bug goes backward at 30 mph, a 90 mph sudden speed change, presumably assuring that all occupants of the VW go on to their eternal reward. (Safety is why VW stopped making that bug, originally conceived of by Germany during WWII; VW in German means the peoples car.) There is only so much you can do about weight the laws of physics, so I have always been hesitant about cars of the 3's size. BTW, the safety rating you see are for cars of the same class. It would make more sense to do them with the "other" car being of average size. The 3, at around 3800 lbs, weighs about 300 pounds more than a loaded Honda Accord. Anyone given thought to the big picture safety issues in a world full of large SUVs and pickups?
