Google is designing its own self-driving car and has plans to build a fleet of cars it dubs “robo taxis,” blogger Jessica Lessin reports. The news comes on the heels of Google Ventures investing $258 million into the personal mobile car service Uber, a company now valued at $3.5 billion, according to TechCrunch
