Uber users in Pittsburgh, USA, might be surprised to find that their next lift is in a self driving car! In Mashable’s first-hand account of what’s it’s like to be take a ride in a self-driving Uber you’ll notice that, like Tesla, that Ubuntu helps power Uber’s self driving smarts. And TechCrunch’s Signe Brewster, in a write up of her experience in the same vehicle, says she “came away from my ride trusting the technology. The self-driving car detected obstacles, people and even potholes, and responded intelligently.“Sadly none of the press coverage (at the time of writing) delves too deeply in to the technology stack being used here, or in other similar cars. But we’ve all seen enough shaky cam screen grabs to know that Linux is the engine of choice being used under the hood of the automotive industry’s self-driving experiments.
