Cars of the future

A car that drives itself must know what other cars are doing, which means managing a lot of information. At Carnegie Mellon, Platzer and his colleagues write computer programs that test the safety of self-driving cars. He says that self-driving cars will probably not be available to buy and use within the next few years, but they’re getting closer. Already, some new cars come with automatic braking systems and warnings that alert drivers to dangerous situations.
