Inbetween Tesla’s announcement that every car in production will now have the capability for utter autonomy by two thousand eighteen and the Obama administration’s plan to invest almost $Four billion in autonomous vehicle research over the next ten years, the race to create the best driverless car has never been sexier.
The rise of driverless vehicles is going to have a major influence on businesses and professionals. Automated vehicles could substitute corporate fleets for deliveries or transporting employees, for example. And workers could build up productive hours in the day by working instead of driving during daily commutes. Innovations in this field are also poised to fully switch the car insurance industry by reducing accidents—a fresh report predicts that accidents will drop by 80% by 2040.
But, what does "autonomous driving" truly mean? In 2013, the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) defined five different levels of autonomous driving. In October 2016, the NHTSA updated their policy to reflect that they have officially adopted the levels of autonomy outlined in the SAE International’s J3016 document (you can download the utter, 30-page document for free here) .
The NHTSA is "working to convert government for the 21st century, harnessing innovation and technology that will improve people’s lives," according to a representative. "This is an area of rapid switch, which requires the DOT and NHTSA to remain limber and adaptable as fresh information and technologies emerge. Amid that rapid switch, the North Starlet for DOT and NHTSA remains safety."
It’s significant to reminisce that the levels of autonomy describe the system, not the vehicle, said Bryant Walker Smith, professor at the University of South Carolina School of Law and School of Engineering and one of the top experts in the driverless cars world. "A Level five automated driving system could be in a vehicle with or without a steering wheel," he explained.

Here’s what you need to know about levels 0-5. The thickest difference is that, embarking at Level Trio, the automated driving system becomes able to monitor the driving environment.
Level 0: This one is pretty basic. The driver (human) controls it all: steering, brakes, throttle, power. It’s what you’ve been doing all along.
Level 1: This driver-assistance level means that most functions are still managed by the driver, but a specific function (like steering or accelerating) can be done automatically by the car.
Level Two: In level Two, at least one driver assistance system of "both steering and acceleration/ deceleration using information about the driving environment" is automated, like cruise control and lane-centering. It means that the "driver is disengaged from physically operating the vehicle by having his or her palms off the steering wheel AND foot off pedal at the same time," according to the SAE. The driver must still always be ready to take control of the vehicle, however.
Level Three: Drivers are still necessary in level three cars, but are able to fully shift "safety-critical functions" to the vehicle, under certain traffic or environmental conditions. It means that the driver is still present and will intervene if necessary, but is not required to monitor the situation in the same way it does for the previous levels. Jim McBride, autonomous vehicles pro at Ford, said this is "the thickest demarcation is inbetween Levels three and Four." He’s focused on getting Ford straight to Level Four, since Level Trio, which involves transferring control from car to human, can often pose difficulties. "We’re not going to ask the driver to instantaneously intervene—that’s not a fair proposition," McBride said.
Level Four: This is what is meant by "fully autonomous." Level four vehicles are "designed to perform all safety-critical driving functions and monitor roadway conditions for an entire journey." However, it’s significant to note that this is limited to the "operational design domain (ODD)" of the vehicle—meaning it does not cover every driving screenplay.
Level Five: This refers to a fully-autonomous system that expects the vehicle’s spectacle to equal that of a human driver, in every driving scenario—including extreme environments like filth roads that are unlikely to be navigated by driverless vehicles in the near future.
Why it matters
So why are the levels significant? They serve as general guidelines for how technologically advanced a vehicle is. In terms of what consumers need to know, Thilo Koslowski, former analyst for Gartner, thinks that ultimately, there are three stages that will be relevant: "automated, autonomous, and driverless." It’s significant to distinguish inbetween "autonomous" and "driverless," he said: "driverless is a more advanced stage of autonomous."
But while drivers themselves may be less worried with the distinctions, the differences could be significant when it comes to issues like car insurance, which is expected to switch radically in the era of self-driving cars.
KPMG, a consulting stiff, has issued a report on how the car insurance business will be affected, since the number of accidents are predicted to go down 80% by 2040. The different levels are significant because they "switch the risk profile of the car," according to KPMG accomplished Jerry Albright. "Insurance companies need to understand how these fresh capabilities affect driving risk." Joe Schneider, managing director at KPMG, put it this way: "It’s like a baby, going from crawling to walking to running."
Albright said, "The car becomes safer and safer as it moves towards fully-autonomous driving."
