text: People have been fascinated with driverless cars since the late 1950's. For example, in the late 1950's, General Motors created a concept car that could run on a soecial track. this track had been embedded with an electrical cable that sent radio signals to a receiver on the front end of the car. Engineer at Berkeley tried the same thing but this time they used magnetics with alternating polarity. The car would read positive and negative polarity messages in Binary code. The "smart-road" systems worked surprisingly well, but they required massive upgrades to the existing roads, but they were way to expensive.
