Nader covers a number of topics, including auto safety. Among the key points he makes is that (as of 1968), the contribution of the automobile itself to accidents was simply not legible, in the James C. Scott sense (Seeing Like a State), to the point that police accident report forms had no options for noting the contribution of the vehicle to the accident.
Built environment and highway design are another factor, of course, but the Nader interview came immediately to mind. I've listened to it several times, and it bears a few more listens as well.
(The Studs Terkel Archive itself is a true gem and recommended for those who enjoy podcasts.)
