You might be surprised. It's a bit more than having to just program in new GPS coordinates. Imagine the car drives the route once collecting tons of data with the laser range finder and other sensors on the car. Now they let the car sit for a few days while they process all the data. Finally the car can drive the route. There's still some pretty hard challenges to solve in making those offline algorithms realtime. Maybe some of it is just waiting a couple years for faster processors, but I'm guessing they might have some pretty intense engineering challenges ahead.
