Anything that takes the driver's eyes away from the path of the vehicle, their attention away from driving, and results in an unpredictable response from the vehicle is a very bad, very unsafe thing to have in a vehicle. The backup cameras are one such thing as you must be looking forward to use them, while the vehicle is traveling in reverse. That is a great recipe to back right into the path of another vehicle that was outside of the limited camera range/angle. All of the "infotainment" stuff is another distraction in a lot of cases- you are fiddling with it and not keeping your eyes on the road in most cases. The absolute worst is the "eco pedal" here. Pushing the throttle and getting a variable response dependent on the whims of the computer is very dangerous. You don't get enough warning in emergency situations to think about "oh, I need to go through the vehicle menu to disable the Eco Pedal, and then I can try to avoid hitting that guy who merged into my lane going 30 under the limit while not being hit by oncoming traffic." A fully self-driving car would be even worse as you would be paying NO attention in most cases to the driving. If it has a hiccup, you will crash before you even know what happened.
