This video is not footage of the Delorean’s safety crash test and it is often incorrectly shared as it failing the test.
It is footage of an independent study conducted by the NHTSA on the effectiveness of retrofitting airbags to vehicles that didn’t come with them. Delorean provided some prototype cars with no glass and doors that couldn’t latch properly for this test.
You can read the final results from the paper yourself

“Although the outward appearance of the crashed vehicle looks as if the crash was quite severe (Figures 39 through 41), the opposite is true. The vehicle crushed approximately 44 inches but the intrusion into the passenger compartment was again confined to the lower firewall/toeboard area and some console axial collapse (Figure 42)”
“Second, the Delorean proved to be a very well designed vehicle in terms of allowing a relatively great amount of front end crush without adversely compromising the “survival space” in the compartment.”
The point of a crash test is to evaluate how well the passengers survive, not how well the car survives, you want the car to absorb all the forces and be a wreck afterword.
