A 1942 article predicted that by 1955 we'd all be flying helicopters to work:
The Coming Air Age (September 1942)
"Let us peer briefly at 1955 and see how your wife handles a typical family helicopter as she flies fifty miles to spend an hour with a friend.

Seated in the two-place cabin, she presses a clutch that applies the engine power to the wheels. For this is a roadable model; she does not have to push or pull it to the lawn. The helicopter drives itself out of its garage to a suitable space near your badminton court... She permits the machine to ascend to 1200 feet... She turns the machine to the left to pick up the plainly marked air route to her friend's home... In thirty minutes she sights her friend's house."

In 1955, an industrial designer made some predictions about the cars of 2005. Many of his predictions were accurate. Others less so...

"Perhaps the driver will wear wrist electrodes. Or the steering wheel may transmit the body impulses. That steering wheel must, by all means, be mounted on a telescoping column..."
