First of all the Model 3 does not have lowest probability of injury, NHTSA explicitly stated that Tesla misinterpreted their statistics.

Secondly NHTSA only tests a portion of all the vehicles on the market, in mass-independent inelastic collisions. That is a limited test scenario against real life situations.

Finally it’s NHTSA tests are the easiest, least stringent out of all the major testing standards. IIHS is the standard to go for in the US since they test things like active safety systems as well.

The most you can say is Tesla does the best at NHTSA test, amongst the limited number of cars they test in the first place.

If you want to see what an actual impressive crash test looks like, look up carbon fiber tub cars like the ones made by McLaren. They crashed the same chassis in 5 different crash tests and it was literally indestructible and survived each one. Now imagine one single Model 3 being crashes in all the crash tests...

I highly recommend you throw away your bias and do a bit more detailed research before creating contents like this.
