You're missing the point - at the root of all societal discord is an intellectual and emotional disconnect, which is, practically speaking, now easier facilitated by technology. That is, people fueled by hatred are much more driven and capable of mobilizing with technological advances than groups who wish to address the root causes. Driverless cars are simply a "feel good" development, along the lines of bariatric surgery. I'm talking about getting deeper into the human psyche for the benefit of all mankind, which isn't a "negligible" type of pursuit. Also, if society valued lives via driving, people would be subjected to more rigorous testing using technology, not simply cut out of the loop.
