SAN FRANCISCO (AP) — The latest models of Google's self-driving cars are now cruising the streets near the Internet company's Silicon Valley headquarters as an ambitious project to transform the way people get around shifts into its next phase. Google announced last month that it would begin testing the curious-looking cars last month, but hadn't specified the timing until Tuesday when it disclosed the vehicles are driving up to 25 miles per hour on the roads around its Mountain View, California, office. If all goes well, Google hopes to gain regulatory clearance to remove the steering wheel, brake pedal and emergency driver from the prototype.
