To be fair, cars are designed to break in a car crash for safety. If it breaks it can absorb the impact a lot better and therefore make the crash more survivable.

Cars are themselves a symptom of a broken system designed to maximize waste. It's wrong that the majority of people even need one to begin with.

Even when it is replaceable, it's ridiculous. I accidentally pulled off the front bumper of my Prius by scraping it on a parking barrier and it cost me $800 because they had to replace a huge amount of the front of the car. The dealer wouldn't even touch it. They said it had to go to a body shop. It's the fucking bumper!

Definitely want to see cars (and other larger purchases) more able to be repaired in future. However, especially in cases of an accident there's other factors.

Part of it as already mentioned is a safety thing. Crumple zones and the like are there to purposefully deform so that the people inside the vehicle have a higher chance of surviving a crash.

Part of it is that being hit in the wrong way can also weaken the structural integrity of the frame making it unsafe to use. Makes more sense to strip it for parts at that point. Last thing a repair or insurance company wants is to be found liable for saying "yes the car is repairable/safe to drive", then the front falls of on a highway.

Part of it also is that insurance companies won't want to pay for repairs that amount to more than the cost of replacing the entire car if it's older. Or they know they can make more money by paying out a policy then repairing and refurbishing the vehicle.

When I buy a vehicle, I touch it, if it's solid metal hey awesome, if it's plastic or fiber whatever I just nope out because I've seen what happens when they're in the smallest of accident.

I can pull a ding out of metal, or even just stop by pull apart and pop a replacement door or whatever off something similar. Can't do that when half the frame shatters in impact, might as well buy another car which is exactly what they want us to do
