Its been cleared to take to the skies for more than a year - but thats not much use when youre supposed to be able to drive it, too. But now the flying car has at least been declared officially road legal. It means the Terrafugia Transition could be in US garages as early as next autumn, after two years of delays. It may not be the worlds first flying car, but its makers say it is the first to have wings that fold up automatically at the push of a button. It costs $200,000 - about the same price as a Ferrari - and can be reserved online for what Terrafugia describes as a 'modest $10,000 deposit. The National Highway Traffic Safety Administration has officially announced the Transition, called a 'roadable aircraft by its makers, can now be legally driven on Americas roads. It granted the vehicle special dispensations, which allow it to use airplane-style plastic windows instead of the safety glass usually used in cars, as it would be too heavy. The polycarbonate windscreens can withstand the impact of birds, so they wont fracture. The administration has also granted Terrafugia permission to use heavier-grade tyres, which are not normally allowed on multi-purpose vehicles. Its the second hurdle the Transition had to overcome before it could go on sale, after the Federal Aviation Administration ruled last year it could fly with its current weight, 110lbs over the normal legal limit for light sport aircraft category.
