I too was a fan of the DS, although I could never have afforded one, but rose tinted hindsight cannot hide the fact that a DS would fail any safety test that cars face these days. It wouldn't score more than one in any of them. The only contemporary cars that might have a chance would be the Volvo 24*. the Saab 900, and most Benzes. Not one of them would score more than 3 in the NCAP. There are a trillion examples of this out there, none more enlightening than this one:
