Huh. Last Thursday, DARPA announced a workshop for Transformer. That is, their flying car program.
"The objective of the Transformer (TX) program is to demonstrate a one- to four-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"
Sounds like something as small as a Jeep, but as easy to shoot out of the sky as a Helicopter. The Sphere goes on to recount the not-so-brief history of failed and embarrassing flying cars. We'll see what some government money does for the situation, but I think they've got it wrong: instead of making cars fly, how about they put road going wheels on jets?
