Waymo now says that experience was crucial in guiding how it approached self-driving cars. Rather than aiming for so-called “level 4” autonomy, where the car can mostly drive itself but a human needs to take over in emergencies, the company decided to jump straight to “level 5” – where a human driver is never needed. Their experience was that human drivers simply weren’t capable of serving as a back-up to a nearly-but-not-entirely infallible robot.
The reality in the end is that although full automation is the goal, companies like Uber are still reliant on humans to step in when needed and this is easier said than done.
