text: Aso some people know, before you can maake these cars you have to have if approved and make sure they are safe enough to be on the roads. Traffic laws are written with the assumption that the only safe car has a human driver in control at all times. As a result, in most states it is illegal even to test computer-driven cars. Even if traffic laws change, new laws will be needed in oreder to cover liability in the case of an accident. Google has had cars that could drive independently under specific conditions since 2009. People would probably like to know what specific conditions they are refering too.
