The cell phone changed how we live, the rest has all been incremental. I'm not living any better since the iPhone came around, or Uber, nor will I because of a self-driving car.
The cell phone changed how we live, but those of us who grew up without it don't think it's all benefit. Used to be life and work were separate, now many of us are expected to be available 24/7.
Self-driving cars, on the other hand, I would love. I hate commuting. The years I lived near a train line were fantastic. My car didn't leave the garage for nearly a year and I liked it that way. Sure, I'd rather have ubiquitous high-quality public transportation, but a self-driving car would be a close second.
Note that the down side here is that as commuting becomes less tedious people will accept ever longer commute times, and we'll keep moving further out, driving down the value of public transportation even more. So yeah, there's that.
