Google just secured the patent for autonomous cars. U.S. patent number 8,078,349 describes a vehicle that can switch from regular human-operated driving to autonomous mode at the push of a button. The driver will need to direct the machine to a predefined "landing strip", and a "reference indicator" combined with GPS coordinates to allow the vehicle to know its exact location.

And now that they've got the patent, start looking out for more driving tech from the search company. For sure!
