Electric cars are great.
Autonomous cars phoning home, spying on people, recording, logging, data-mining, slicing, and dicing their trips are a fucking awful idea.
As far as pedestrians — there need to be better means than “footbridges and elevators” to address the issue before lights and stops go away. Imagine how many crossing points, lights, stop signs there are in the US as a whole, then imagine the cost of bridging each one.
Frankly, let’s hope that North Korea orbitally smacks the HQs of a few firms working on this self-driving shit before it gets lobbied into existence. Or just hacks them into the stone age.
