The Concept: Programmable computerized golf carts that would let golfers check the score of any other cart on the course in the same game, locate the position of their ball, and order food and drinks. The carts would also offer topographical information for any green.
The Rationale: As baby boomers start to retire, golf will become even hotter. The carts would up the pleasure factor.
Reality Check: What's next? A machine to hit the ball?
