There are no autonomous vehicles—yet | TechCrunch


because it requires no human input during that time. He’s not wrong. But this is misleading.Not long ago, I published a guide to the SAE levels of autonomous driving, and it’s there I’ll turn again for clarity. The cars with the most cutting-edge automated driver assistance systems, or ADAS, are at Level 2 or 3 at best. Here are the full nerd-speak definitions from SAE:Level 2: Partial Automation. The driving mode-specific execution by one or more driver assistance systems of both steering and acceleration/deceleration using information about the driving environment and with the expectation that the human driver perform all remaining aspects of the dynamic driving task.Level 3: Conditional Automation. The driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task with the expectation that the human driver will respond appropriately to a request to intervene.Note that in both levels, the human driver is still expected to be able to take over. Level 4 requires the vehicle to handle driving tasks even if the human does not respond to a request to take over, such as if he’s asleep or incapacitated. Level 5 does all the driving all the time, no human input required. That kind of autonomous driving does not yet exist, even if it’s called Autopilot.“But Google has autonomous vehicles!” you cry, probably on Twitter. That fleet is experimental. You cannot buy those cars. If you did, they would probably not work where you live. The fleet only works in cities where it is being tested—Mountain View, CA, and more recently Austin, TX—in areas that have been mapped within an inch of their lives. And even then, as of 2015, Google’s autonomous test cars have been used in fully autonomous mode 57% of the total number of miles driven, according to a University of Michigan study.Even the vehicles with the most advanced ADAS features today are not yet fully autonomous. ADAS will keep your car a set distance behind the car in front of you. It will in some instances bring you to a complete stop. It will keep you from drifting across lanes. It will prevent you from backing out of a parking space into someone else’s car. It’ll even get you into that parking space in the first place. It’ll prevent a lot of accidents caused by the fact that our attention is often pulled elsewhere while we’re driving.
