text: Some people may argue that there are beneficial sides to an autonomous car, and of course there are. These cars would cut down our costs on gas, they could even be safer than some humans driving cars, and they could all be traced around on a track designed just for the cars. But it all comes back down to cost. The thought of replacing all roads with "Smart Roads" is not only seemingly impossible, but timewise it would take a lifetime. If every single road was taken apart and rebuilt all over America, the world even, it would take at least 10 years, and the cost would be enormous. And these cars are safe, but if that situation ever hits, no one is going to want their death or disability caused by a car driving on its own because of human error, yet again.
