I agree with what you said. I am sure that MB has made some things simpler and better...like the switch and wiring you describe. The features you describe, the ABS, the ESP and the ASR, I agree with you on that. Those are safety features. However, I think most of us could survive just fine without Distronic, Keyless Go, ABC, Command and electro-hydraulic brakes just to name a few. And we might even appreciate the benefit of less hassle when the stuff breaks..."when" not "if", since that is more or less inevitable. So for every wire that MB has reduced, like the power door switch, they have added 1000 more somewhere else on the junk named above for example.
