So your husband like's the Nanny features? I don't know but I'm old school I guess. I have the features mentioned and I could care less. I don't text and drive so wondering is not an issue for me. My coach came with those "safety" features. But if I had to pay extra for them I definitely would not have checked the option box. I have a 2013 MB E-350, if I open my door while backing up to see behind me the car pops out of gear. Apparently it thinks I'm drunk and I'm going to fall out and run over myself (Darwin at work
. I miss simple non-intrusive electronics.
