Security ... think about it!
"The objective of the Transformer (TX) program is to demonstrate a 1 to 4 person transportation vehicle that can drive and fly, thus enabling the warfighter to avoid water, difficult terrain, and road obstructions as well as IED and ambush threats. "The vehicle will be capable of driving on prepared surface and light off-road conditions, while flight functionality will require Vertical Takeoff and Landing (VTOL). In addition, range and speed efficiencies will allow for tactically relevant missions to be performed on a single tank of fuel." In other words, flying car. Or at least some sort of ground effects vehicle.
