As others have pointed out, this is really pretty irrelevant when it comes to any individual car being out-of-date safety-wise on a ~decade time scale. Completely ignoring differences in vehicle size, my old, small sedan had no side-air bags, no ABS, no rearview camera, etc., and these days every small sedan must have those features. Things are only more dangerous to pedestrians if I decide to replace my small sedan with something like a Hummer, but that's an orthogonal decision.
