I believe Ford made a big deal out of their padded dashboards in the 1950s as well but I would have to dig up references to that.
While Volvo has a great safety record they are not even close to the only manufacturer with a history of adding safety features to their cars. Safety is good business, the US domestics have known this for decades.
The 1971 Oldsmobile Torornado brochure prominently features ABS and specifically calls out the safety features available in that year: http://www.lov2xlr8.no/brochures/olds/71toro/bilder/6.jpg
