ARD Auto+Traffic: Straps are missing in many cars

Hi, was yesterday at the ARD: => Severe injuries due to missing belt strap at the rearhttp://mediathek.daserste.de/…/…backseat-in-fond Summary: -Ford and Opel no belt strap at the rear -BMW: only belt strap at the 7’er -Volvo+Mercedes: standard for all models ! -VW-Passat: belt strap at the rear can be ordered (with side airbags at the rear) -Audi: only A8 In the configurator of Audi, I found side airbags at the rear but nothing from belt straps at the rear I don’t understand why, for example, BMW invests so much money in safety and then saves some toads in the belt spacing.
