The Federal Aviation Administration has granted a weight restriction exemption to flying car manufacturer Terrafugia that could pave the way to flying cars being more viable. They allowed for an extra 110 pounds for the company's "Transition Roadable Aircraft" so now it can have airbags, crumple zones, and a roll cage, which are all things required to drive on the road.
From the Aircraft and Pilot Owners Association newsletter:
Still to come is approval from federal highway officials regarding non-waiverable highway crashworthiness standards. Without that, the vehicle can't be marketed as a roadable vehicle. There is no timetable for a decision, but company officials are hoping to hear this year. Company officials feel the extra weight allowance by the FAA allows for the weight of the structure needed to meet highway safety standards, despite the FAA approval falling 44 pounds short of the request.
