text: Currently, only a few companies are working on driverless cars. Some of these companies include, General Motors, Google, and BMW. The birth of driverless cars started with special tracks that the cars could drive on. In the late 1950s, General Motors worked on a car that would run on a certain road. This road sent radio signals to the car itself and this is how the car would drive. This supported the idea that we didn't need a smarter car; we needed a smarted road. This system worked incredibly well; however, this idea was too expensive. After the reality of special tracks failed, engineers started working on smarter cars. This created a problem at first because the technology was not yet advanced enough to create driverless cars.
