My 2015 S 70D is much better at recognizing speed limits than your Mercedes. Gets it wrong rarely and in fact notices signs that I miss. There is one parallel road where it persistently incorrectly recognizes the speed limit as belong to the road I am on bt that's just one out of many of thousands of km of road that I have driven in the car over the last 18 months.
