Closer Than We Think! Magic Beam Highway (1961)
This Closer Than We Think! strip ran in the October 15, 1961 Chicago Tribune.
The government may soon build an automatic highway, on which drivers can look the other way while electronic controls pilot their cars.
One type of robot road has already been demonstrated by General Motors and RCA. Guidance strips and loops in the pavement receive electric impulses which are picked up electronically by a control box on your car. The impulses regulate direction, speed, braking and obstacle detection - so the car can be guided automatically, without possibility of accident. All you need do is take over when your car gets to the end of the automated section!
A 100-mile test route may be operating by 1964, say Washington reports, and major highway robot systems may be in use by 1975.
