It is expected the Apple Car will be able to drive itself. Apple with its tremendous technical skill in the software and hardware domains and its extensive work building Apple maps is in an obvious position to develop a self-driving car.
Aside from the technology there are a lot of regulations which would be subverted if cars drive themselves. All driving regulations assume a human driver. A driverless car could not be allowed on the road according to present day law.
However, if the government agrees to accept the computer in the car as a driver, then it opens the door to widespread legal use of self driving vehicles.
In the current article, Reuters got a copy of a letter the USTO sent to Google agreeing to consider their computers as a driver thereby marking a major landmark in the history of the automobile.
In addition to Google, this would also of course benefit Apple and other automakers who will be making such vehicles.
