For a start everybody'd have to buy a box to be fitted to the car. I wouldn't know where to end with likely societal problems that would tumble out of there.

For a system to work, the people who are inconvenienced by it have to have a buy-in over their current arrangement. That's simple psychology, yet from my experience, techies ignore the human dimension almost entirely.

But it's all neither here nor there, give it 5 years and I'm none too convinced there will anything like as much driving as there is now. Average wages are falling, cost of petrol is rising. something's gotta break.
