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?

For the driver, full roll cages, the seats, the helmets, the head and neck safety devices. For preventing the rollovers, there are flaps that get blown up by the air moving over the car when the car spins that act as air brakes to help keep the car from rolling or going airborne.
