What is it that makes Nascar cars so safe during crashes? I’ve seen cars wreck out at nearly 200mph and it looks like a bumper car crash.

Question

I’ve seen Nascar crashes where a car going 180 goes sideways into a wall, and then gets t-boned by other cars that were also going 180 mph and yet no rollover and the cars barely look damaged and everyone walks away unscathed. Meanwhile normal passenger cars go sideways doing 50mph and they roll over 6 times, gets demolished, and kills the driver. What is it about Nascar cars that make them so crash resistant/resilient?

Street cars are a compromise between safety and convenience. If you’re willing to crawl through the window, sit in a seat that pretty much fully wraps around you, wear a harness so only your arms and legs can move, and a helmet, you can have all of the same safety stuff. I had a Polaris RZR and put racing seats and harnesses in it. You can’t even reach things like cupholders after that.
