You can die in any vehicle, no argument, your survival chances are higher in a big vehicle, this is not just my opinion. Crash test are done with a stationary wall to access crush factors and g forces on dummies. In a real head on crash the wall is moving at you if you both have the same mass you both stop, the car with the longest shock absorber a experiences lower g loads for a longer time then the car with a short shock absorber, shock absorber = crush zones between you and the bumper. My daughter started driving about two years ago, junior license for first year, when it came time for her own car about a year ago I bought her a large vehicle (super crew pickup) for safety reasons ,one hopes to never test the safety of their car. We were not so lucky, this summer she lost control in a turn 1/2 mile from the house, rain had just started and she was going around a turn that has claimed others over the years. My daughter was removed from the cab after an hour by the medics, on a back board through the windshield, and taken to the hospital, by the time I reached the hospital she had been released with a clean ticked. Later during my meeting with the state police crash investigator that was on the seen, I was told if your daughter had been in a small car, we would be having a differant discussion. The car went down a embankment hit a culvert pipe concrete end plate and rolled 3 times, it was a violent crash. I bought her another Ford super crew pickup.
