“Why? Taller. Stronger. I mean, the elephant, the bigger you are, the more chance you have to survive. Now, we know that the higher you are, more chance you have to roll over. And we know that SUVs have a higher rate of accident for rollover than other cars. I mean a Porsche is a lot less chance to roll over than an SUV.

So Porsches are safer, right?

That's at the cortex, which means people know it but they don't refer to it because there's something stronger which is the reptilian- the bigger, the tallest, and more chance to survive.”

Try F=ma. Sometimes people's reptilian brain knows more physics than their cortex. Most people have an understanding--whether they can articulate it or not--that the mass of a freight train protects its driver in a collision. That intuition is correct.

in a crash, the ability of the frame to dissipate energy and maintain a protection zone around the driver is the key to safety.

Actually Corvettes have one of the highest rollover rates of all vehicles, but it is rarely mentioned. I'm not sure where the actual experience of Porches is for roll over, but it could also be high.
