text: As explained in the article, two seperate companies already came up with patents for driverless vehicles. They used electrical cables/ magnents within the road to create a path that the automobile could follow. As said in paragraph three, these ideas worked surprisingly well, yet they were too expensive to be practical. This idea was invented decades ago; everything was cheaper back then. Now a days, this idea also seems inpractical. the cost for these "smart cars" will remain insanely costly. the manufacturors will be out money because the people won't be able to afford these high priced gadgets.
