Since the moment that video went online, every single human in the world with even a passing interest in cars has seen it, and a pretty high sampling of those humans immediately went to some online forum and began pounding the keyboard in an incandescent, ungovernable rage. This continues to the present day; right now, some elderly gentleman in Indiana with his very first internet connection just watched the '59 get trashed by the '09 and found some old-car-guy site upon which mash the CAPS LOCK button and bang out the comment "I NOT TRUST MY LIFE TO TAHT NEW SO CALL CHEVVY HA HA NO WAY GIVE ME REAL CAR DETRIOT STEELE THEY LIE LIKE OBAMA."
Several seconds later, some kid with a cracked-glass iPhone and a Hyundai Accent with eBay coilovers will thumb out a similarly allcaps rant about his disapproval of American cars. And so on. The point is, it was not possible to discuss this crash test. Six years later, however, everyone (except the aforementioned online newcomers) is so weary about arguing about it that perhaps we can have a reasonable discussion on the subject. Say, about the X-frame of the '59 full-sized Chevy, or the fact that the curb weights of the two vehicles were very similar, or the effectiveness of airbags/collapsible steering columns/crumple zones/whatever.
So, take a deep breath, remember how weary you became with jeremiads, screeds, tirades, and fulminations over this video back in '09, and share your most rational, non-Culture-Wars-tinged thoughts on what we really learned from this crash.
