Nissan's Pivo concept car elides the need for three-point turns -- instead, the entire cabin spins around so that you're suddenly facing in the other direction.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
