Whenever the encyclopedias I inherited as a kid were written, they thought cars of the future would run on tracks and automatically alleviate traffic. Now we're on the cusp of realizing that vision in a different way than they envisioned but I think our culture has the same tunnel vision it did sixty years ago.
Most folks are still thinking about cars. What we should have been thinking about sixty years ago is still what we need today. Viable, affordable, widespread, ecologically sound mass transit and an end to the obsession with privately owned and operated cars.
If obsessing about maglev could get us to the mass transit equivalent of where we are today with self driving cars, I'd be the biggest fan ever.
I'm still a pretty big fan though.
