text: Four states have already approved the limited use of driverless cars. "California, Nevada, Florida, and the District of Columbia have lead the country in allowing limited use of semi-autonomous cars." This information helps to prove that the idea that the idea of driverless cars is slowly but surely being accepted. California and Florida are large states that have a large population and get a lot of tourists every year. Nevada contains Los Vegas, another huge city, and is a place where a lot of people got to gamble. Finally the District of Columbia houses some of the most important buildings and artifacts of the American government. These are all states that mean a big deal, and since they have accepted driverless cars that means that they could spread extremely quickly to the other states. If some of the biggest most populated and most important states can accept the cars then that means that the bettle is almost won and is proof that driverless cars are a good idea.
