cartechboy writes "Follow the thinking for a second. Google drops $258 million into the car-taxi app Uber. Google says it will make self-driving cars available within four years, based on its ground-breaking research into self-driving cars. Tesla CEO Elon Musk has spoken with Google about driverless technology for future Tesla vehicles. So, are we watching the assembly of a massive driverless taxi service of the future? Battery-electric vehicles make excellent autonomous taxis (very few moving parts, low per-mile energy cost, and zero noise or emissions) Could Google use some of its cash hoard to buy Tesla outright (making Elon Musk its third largest shareholder in the process), then grab Uber and turn the whole thing into an app? Musk's goal has always been to transform the very nature of transportation. This might just do that."
