As has been variously noted along the course of this thread:
- The basis of the changes is United Nations Regulation 79 PDF here - not the EU, not anyone else.
- The changes became effective in 2021 in order to pave the way for Level 3 Autonomous Vehicles to be permitted in Europe and elsewhere (Report here)
- The impact on Mercedes-Benz: anything below the S Class does not have fine enough sensors to comply with the new regulations.
I received a new C Class (build date January 2020) with parking and driving assistance plus packages. Two features: self-parking as advertised, and automatic lane changing on motorway when cruise control engaged - just signal and the car does the rest. February this year the car was written off after a collision at 80 kmph on a priority road with a car that failed to stop when emerging from a side road. A near identical model (build date December 2020) has the same packages but both of these semi-autonomous features are missing, and the VIN decoder includes an entry 8B8 Active Parking Assist Reduction (UN R79).
That Mercedes-Benz can be held culpable for compliance with UN Regulations for the Automotive Industry, I think not. That their dealers appear to be woefully ill-informed about the changes - certainly, but the likely redress is highly questionable. Can the features be (re)enabled... I guess, unlikely.
