Audi, Daimler, Volvo re-think automation

From the moment they were created, the pair known as "Heidi" and "Erin" were destined to be with each other their whole lives -- or at least as long as their Audi A7 wasn't involved in a crash. In Neckarsulm, Audi's most flexible plant, driver-side airbags are named after girls, while the steering wheels have boys' names. Other components are designated according to seasons or places -- anything to help make it easier for production workers to remember when sorting and installing them.
