Self-Driving Cars

but if I'm in a self-driving car I assume I'll be way past the grocery store by the time I even call up the screen to enter my new destination. What is needed is a quick way to instruct the car to "turn right here."

Will there be an easy way to give a self-driving car a series of instructions that boil down to, "Turn left at the next light; turn right in three blocks; turn left at the Exxon station; stop here."
