I like the idea of a self driving car for most of my trips, but I also love to just go for a drive sometime, and it feels like the later has its days numbered.
I imagined, that a 'smart' car would briefly show you ads on the windshield before agreeing to follow the course, and while on the go, would then time-to-time briefly shade the windows (or whatever is the primary outlet of attention) just to show you another personalized ad. Time to step out? Wait a sec, another ad, just to unlock the door... Captive is the word.
But a computer looking over my shoulder and second guessing me makes the process of driving even more awful and complex.
