It was 1972 and Bosch was testing a navigation and information system—decades before GPS was invented. It cost ~$55,000 per mile to instal on the road. It’s a study of how unrelated technologies can supersede the conception of the problem. The navigation answer was in the sky.pic.twitter.com/obPGH2a09F
John, yes! Etak. I did not use it but it seemed to work well in some areas. It was just not aware of most roads in many cases. It is interesting how these systems have evolved.
