i see the difficulties production wise however manufacturers have been guilty of launching cars with spec that they later take off and put in add on packs at a price.
also many feature dont have an off switch or if they do its near impossible to find.
i cant operate touchyfeely screens so having one would be a danger in a car for me.
the mini system is fine a big button inbetween the seats turn the dial and press for your option. same with the aircon two big dials for you to twist one for each side of the car buttons for the rest. easy to find and operate.
i dont need or want ideally radar braking that is set off when large leaves blow in front of the car.
as to what i do need its a high driving position easy to get in and out of an automatic , ability to play music from a usb rather than attempting to link a phone or music download list again more distractions and menus to search through your supposed to be driving not browsing the internet.sat nav is useful and i prefer leather if its affordable within the ap. other than that you can keep all the techy self drive stuff.
