text: There are a handful of companies developing prototypes and concept cars, such as Toyota, BMW, Google, GM, Tesla and even apple has attempted at it before, but havent had as much success compared to the brands listed before apple. GM has had Computer driven cars since the 1950's. In 1950 GM created a concept car that could run on a special test track. Of course that didnt suceed due to the expenses the government would have to pay for new roads with sensors and electrical cables which was way too expensive to be practical.
