text: With smarter cars comes smarter roads? Some companies such as General Motors has led themselves to belive if you update roads, putting some type of magnet, or metal device in them to sensor to the cars, they will have no problem driving on roads. Although, that sounds brilliant would it really work? General motors made a smart track, embedding electrical cables to radio signal negative and positive energy to the front end of the car. It was very succesful, but not every road is as smooth runnng as the track was.
