I missed this Elon Musk interview when it came out in April, but it's pretty great. As usual he comes across as a bit unrealistic about what's possible in the short term, but he still tells a pretty compelling story. I especially like the idea of underground car tunnels vs flying cars. ("I sure hope the people up there have kept up with their hubcap maintenance" was a pretty funny understatement.)
