There are also questions about responsibility. If accident happens, who should be blamed, the car , the programmer, or the passenger?

Even with these , many companies are testing self-driving cars, and some already on the road in certain cities. In future, they may become common. Self-driving cars have potential to change how we travel, making transportation , easier, and more comfortable for everyone.
