What Are the Different Self-Driving Car “Levels” of Autonomy?

Autonomous cars seem to be a promise that's here, almost here and that will not come for years all the time. These affirmations are all true because there are different "levels" of autonomy. Here's what these levels mean.

NHTSA has created levels of clarity

If it seems that you have been told that cars can already drive independently and that they can not drive independently, you have heard the message back and forth. The US Road Safety Administration (NHTSA) defines six levels of autonomy of the car. They have published this guide to advance and standardize autonomous vehicle testing.

Autonomous cars could potentially save many lives, but lack of common purpose and agreed rules to test them could erase any potential gains. In the same way, it's easier to know what to expect when you buy a router that complies with the Wi-Fi 6 standardIt is easier to know what to expect when you buy a car that meets a self-driving level.

NHTSA divides autonomous cars into six categories, starting with level 0.

Level 0: no automation

Chevrolet Chevette 1976The 1976 Chevrolet Chevette does not include any automation technology. Chevrolet

A car of level 0 has no ability to self-drive. Humans do all the driving at all times. Basically, a car of level 0 is not autonomous at all. The T models were level 0 cars. If you were born in the 80's, it was probably your first car. In fact, until recently, most vehicles were at level 0.

Most of the used vehicles on the market are still level 0 today, from your 2007 Ford Focus to your 2010 Toyota Prius.

Level 1: Driving Assistance

Chevy Impala 2014The 2014 Chevrolet Impala features adaptive cruise control. Chevrolet

A level 1 vehicle can help steer or brake, but not both at the same time. Adaptive Cruise Control (ACC) falls into this category because it only handles braking (to keep a specified distance from the car in front of you), but not steering.

Some cars already have this technology. the 2011 Jeep Cherokee had ACC, Chevrolet introduced several models in 2015and Ford introduced the first pickup truck (an F150) to include VAC a few years ago.

Level 2: partial automation

Tesla Model SThe Tesla S model is both automated and equipped with braking technology. You're here

A level 2 vehicle can help both direct and brake. They always require all the attention of the driver and you must be ready to take over at any time. If you combine Adaptive Cruise Control from our explanation of Level 1 cars with track centering (which allows you to steer your car towards the center of the track), you have met the Level 2 definition.

GM Super cruise is a great example of level 2. With a car that's geared to Super Cruise, you can get off the wheel. But the cameras are directed towards your eyes and if you are detected while you are not looking at the road, the system will turn off. The Tesla autopilot The functionality, as seen on the S, X, and 3 models (when you pay for the add-on), is currently in the Tier 2 category.

Level 3: conditional automation

Audi A8The Audi A8 offers level 3 capabilities, but not in the United States. Audi

At level 3, you can leave the road eyes. Even if a driver must still be in the car, we do not expect him to be aware of everything, as with the automation of levels 2 and 1. You may still need to take the flying at any time, which poses some difficulties. If the problem is an imminent wreck that the car can not handle, the driver may not have enough time to properly assess the situation.

Audi planned to launch the A8 with a feature called Traffic Jam Pilot, but canceled those plans in the USA. because of the complex legal framework across the country. As its name indicates, Audi limited the feature to slow speeds (preferably to stop and go vehicles, but up to 37 mph) and only to places where a physical barrier separated oncoming vehicles .

Level 4: High Automation

Waymo

A car with a level 4 ability can do all the driving, but only under certain circumstances. Unlike Level 3, you will not be forced to take over when all conditions are met. But if it is raining or snowing, the vehicle may not allow you to drive on your own.

Honda announced that he was working towards a level 4 vehicle from here 2026. Lyft, Uber, Google and many others have long been working on level 4 vehicles, but the reality is that all of their cars require safety drivers and that they test between 2 and 3 standards. Waymo is an exception because it tests at level 4 in the Early Access Program. When you ride in a Waymo vehicle, there is no security pilot (although there is exceptions to this). But they limit the conditions under which vehicles are allowed to drive, in part by testing in Arizona, using generally dry weather as an advantage.

Level 5: Full automation

NumoThe Numo is a level 5 vehicle without space for a driver. Nuro.ai

Complete automation is the noble dream goal that requires no human driver. You could only be a passenger and not be required to drive at all. If level 0 is the car you drive, level 5 is the car driving you. The first level 5 vehicle is already on the road. But you will not see that it carries people, but rather races.

Nuro works in partnership with Krogers to test small cars carrying groceries for a short distance. They leave the store and arrive home. You go out shopping. He's going away.

No human is handling the car and there is not even a steering wheel. By limiting the distance and speed of the vehicle, they reduced the variables to reach their full autonomy more quickly. But cars that drive at high speed with passengers are very far away.

Technology is not the only complication

Technology is not the only problem that automakers will have to solve in the future. The laws must be fully standardized and we must find answers to some important questions. For example, if a fully autonomous vehicle hits another car, who is at fault? The passenger who was not driving? The manufacturer for the faulty code? What insurance pays for the damage?

The automakers will also have to convince citizens to give up their control and trust a computer to control the very delicate course of navigation on our roads. most Americans do not have this confidence.

It is likely that fully autonomous vehicles will be in many years and even in this case they will be relegated to luxury cars. It will take even longer before the technology falls back on ordinary buyers. Lyft, Uber, Waymo and others are working on autonomous taxis, and you can already go there. For some, this might even replace the need to own a car since you could call a car for it to come to you via an app when you need it.

Who knows? One day, our children or grandchildren could look at us with shock considering our dangerous driving habits that have been rendered obsolete by the computer.
