this is the one for me :
the late 1950's issues of " mechanics illustrated" predicted that we would be using "flying cars" within 10 years .
they also predicted that by that time all highways would have an "automatic guide system " .
you'd drive your car onto the highway , punch in your destination and the car would drive you to your destination - the driver could have a nap , eat ... whatever . a few miles before reaching the destination , the driver would be alerted and take the car off the auto guidance and roll up at grampa's house - all refreshed !
