Google is leading the charge towards the production of a fully autonomous car, releasing a video earlier this week of the car being tested on a programmed route.

One Lap of the Web: Senna's sweet go-kart

-- Gran Turismo has always included some, uh, unique car choices for its video games. (Sure, the Patent-Motorwagen is significant, but hot-lapping the 1-hp horseless carriage in "Gran Turismo 4" wasn't exactly riveting, unless you used cheats.)

Plus, if you make it go 352 mph you can finally stick it to Prost.
