CNN has an article featuring Peter Diamandis on the Automotive X PRIZE. The video on the left of the page has much the same information, but you have to get past the commercial to get to the pictures (including autos and gas pumps of course, but also Space Ship One and Zero-G flights).
By the way, the Automotive X PRIZE draft rules were released on April 2 for a 60-day comment period, so I suppose the comment period, so we must be getting to the end of that period (if I could remember which months have 31 days I could say for sure...)
