FYI, the article suggests self-driving cars have been approved in Nevada and California, which is true -- but in both states, a human passager (presumably with a driver's license) has to be in the vehicle. In Nevada, you actually have to have two passengers, which in some cases makes it more inconvenient than regular driving.

So ideas like sending your car home instead of parking it, or sending tractor trailers across the country without a driver, aren't going to be legal for the time being.
