Solar Freakin' Roadways

The possibility of solar roadways seems awesome after watching this video. The idea of roadways providing fiber connectivity and bringing fiber optic speeds anywhere roads run makes me giddy with joy (maybe too much). The ideas presented seem like solar roadways are a no brainer. With the exceptions of cyberterrorism to change the LEDs on the road (Die Hard: With A Vengeance anyone?) and cost, I don't see anything but possibilities here. Unfortunately there is likely to be staunch opposition by those who stand to lose a lot of money in the existing roadway construction industry. Personally, I'd love to see this technology become mainstream.
