There’s another factor at play here, too. Uber executives haven’t been shy about their fondness for driverless cars; the company is partnering with Carnegie Mellon University to work on the technology. After all, robots don’t strike for higher wages, nor do they assault passengers.
Driverless cars need two things to work. The first is on-car sensors, which constantly monitor for changing road conditions that require an immediate response, like pedestrians and stop signs. The second is maps, which tell the car where to go on a bigger scale.
