I’ve never noticed this before but then I’m usually looking backwards when reversing. Seems funny that vw put more lighting on the front of the vehicle than the back when reverse is selected!
Hopefully you're looking all around you when reversing.
As I posted earlier, the purpose of this function is to give some wide angle light at the front so that you can see what the front end is going to swing into. That said, better reversing lights would be helpful too.
