The U.S. Armed Forces have a goal to have one-third of operational ground combat vehicles unmanned by 2015. That's next year. The solution from Oshkosh Defense is the TerraMax UGV, a vehicle kit system, which gives soldiers the ability to control trucks remotely using a controller that will look familiar to anyone with a Mario Kart game.
Top Gear did a test drive of sorts, pitting an autonomous TerraMax against a Range Rover on an off-road course in Nevada. This video is a preview of a race between the driverless TerraMax versus Top Gear's James May; go here for the full 9-minute version.
