The reason your car crumples so much when some idiot hits it is to protect you. The more energy that goes into deforming parts of your car, the less that goes into accelerating your meatbag, preventing injury.
I'm aware of the physics. I just don't care. I'd still rather have an old solid chassis land yacht for several reasons. For one they will survive a wreck. They're cheaper and easier to work on. And they're user serviceable.
I don't have new car money. As that would mean full coverage money. Which I also don't have. Even liability is ridiculously overpriced now.
