text: In my opinion, the cars are not needed because if we are still needed to always be full attention on the road why wouldn't we just drive. Also in with coming the driverless cars it states we need smarter roads. So the cars would only be able to drive on certain roads or every road in America would have to redone. Every road being redone is unrealstic as it was way to costly and time consuming. " These smart-road systems worked surprisingly well, but they required massive upgrades to existing roads, something that was simply too expensive to be practical." Another reason being the safety and changing of the laws. The safety of one car not catching a sensor of another car and getting into a crash. Another safety problem if they driver is driving a driverless car and is to preoccupied with his phone or another task in the car and the car needs the persons assistance and her is to preoccupied then the car with crash. With the law, many new laws would be needed to be created with the development of driverless cars. Only four states have released permission of testing driverless cars as other states are not on board. "As a result, in most states it is illegal even to test computer-driven cars. California, Nevada, Florida, and the District of Columbia have led the country in allowing limited use of semi-autonomous cars; manufacturers believe that more states will follow as soon as the cars are proved more reliably safe".
