Gotta disagree with this one.
Don't get me wrong. There are some amazing vehicles out there that kick the 80's butt in terms of safety features (mostly European ones, where they have
real safety regulations). But there are many current ones that are equal or less than even a vehicle as old as an 80 (the cheaper domestic vehicles come to mind).
Also keep in mind that there is a huge difference between earlier and later 80's. Air bags make an incredible difference in passenger safety.
There's also a bigger difference in design. Older vehicles like the 80 were not designed to crumple, they were designed to take a beating and keep on moving. New vehicles are much more likely to crumple on impact. Each approach has is pros and cons (ask FJC owners about their torn fenders for one of the cons).
Well, I didn't ask any accident recon guys, but I have spoken to my pop who's extricated more than a few folks from vehicles (30 years in the fire service).
He loves my 80's, and has commented more than once that he's glad that my wife (and 10 month old son) cruise around in one. While he thinks that a newer Volvo/BMW/etc would be safer, he also thinks that an 80 is about the safest vehicle you can buy for the price. And I can't disagree with him, given some of the accidents we've seen around here that people have survived or even walked away from. Such as hitting a crane head on a 60+ MPH. Or rolling 4+ times at 70 MPH.
