Two vehicles hitting offset at 35 mph = 70 mph combined force. The odds of surviving a collision of this magnitude, in any vehicle, is slim.

That's what I thought as well, however this week on car talk a phyisist called in and corrected us both.
if 2 cars of the same mass are traveling together at 35 mph each, each car wil experiance the same crash force as if they hit a SOLID concrete wall at 35 MPH.
Think about it, there is 70 mph worth of momentum, but it is divided equally between the 2 vehicles. Now if you change mass, the heavier car will push the smaller car backwards making its impact worse, but most likely not 70 mph bad.
Sorry to grave digg, but this thread was liked from the current safety thread
