Here are examples of how dreamers of the past envisioned real and fictional cars of the future. Some of their ideas might seem outlandish, but as David Szondy of the retro-future website Tales of Future Past noted: "You've got to be willing to get egg on your face, or you're never going to get anywhere."
º 1917 • Curtiss Autoplane
The first of many concepts for a flying car looks like the front of a pickup connected to the back of a plane -- but navigating traffic with its 40-foot wingspan is a bear.
1933 • Dymaxion Car
Inventor Buckminster Fuller's teardrop-shaped three-wheeler is 20 feet long but light, fuel- efficient and inherently aerodynamic.
1950 • Rover JET 1
The first gas turbine-powered car -- based on the then-modern jet engine -- is fast, but it guzzles fuel and suffers from sluggish steering.
º 1958 • GM Firebird III
Concept car godfather Harley Earl's jetlike automobile boasts realistic future features such as hands-free navigation, rear-mounted cameras (to replace mirrors) and joystick steering.
