When can I buy a self-driving car?

Self-driving cars have been around us for some time, and manufacturers seem to be making progress every day. But when do you have a self-driving car in your driveway?

Well, the answer is a bit complicated. To answer that, we need to understand where we are at the moment with self-driving cars and what steps we need to take to make fully autonomous cars a reality in the future.

When is a car completely autonomous?

According to SAE International standards, autonomous vehicles are rated with a "grade" on a scale of 0 to 5. Level 0 vehicles have no autonomy and must be controlled by a human at all times. Level 5 cars are completely autonomous and do not need any help from a human.

The car you are driving is more than likely a Tier 1 autonomous vehicle. It has cruise control capabilities and may even be a reversing camera. However, you may want to drive a semi-autonomous Tier 2 or 3 car, such as a Tesla, a Cadillac CT6, a Mercedes-Benz E-Class, or a Volvo S90. These cars have features like autopilot or super cruise that let you take your hands off the wheel while keeping your car steady and changing lanes.

Okay, the transfigured cruise control is super cool, but you try it Buy a completely self-driving car. Are there any level 4 or 5 autonomous cars on the market? The answer is a clear "no," but you could very soon be in a real self-driving car.

RELATED: What are the various "autonomous levels of self-driving cars"? 2019 is the year of the autonomous cars of the level 4

We have not yet spoken about level 4 autonomous vehicles, but they are an important step on the way to the self-driving car. The dividing line between autonomous vehicles of stages 4 and 5 is essentially flexibility. While Level 5 autonomous cars can travel as far as they can and maneuver safely through novel locations, Level 4 cars remain stuck in predetermined areas such as a city or state. Level 4 cars are also fed with roadmaps and dates that make everything very easy and safe. While Level 5 cars are similar to hyperconscious people, Level 4 cars are like a blind person walking through the streets of a well-known city.

Therefore, Tier 4 autonomous vehicles are built specifically for driverless ride and delivery services, not for the passenger car retail market. These cars drive for a given distance, but they can maneuver between lanes and avoid collisions with cars or pedestrians. They are reliable, safe and well-suited to collecting data useful for Level 5 vehicles in the future. In some cities, manufacturers are already using Tier 4 autonomous vehicles and there is a good chance that you have seen (or have been) a Level 4 autonomous car.

Waymo, the self-driving car company founded by Google , is one of the pioneers of Tier 4 self-driving cars, and has been working on autonomous vehicles for nearly a decade Waymo vehicles are currently being used in Chandler, Arizona and San Francisco, California, to share carpools (by selected individuals) Greater Metro Phoenix, who want free rides in an autonomous Waymo taxi, can now sign up for an Early Rider program, but the number of seats is limited, so you do not spend too much time thinking.

Waymo's Greatest Competitor, GM, released a fleet of self-driving Chevy V this year These Chevy Volts have no steering wheels, pedals or tachometers and they are a sure step towards driverless cars. We do not know where GM will test these cars, but the company has been using Tier 4 (with steering wheels) autonomous cars in San Francisco and Phoenix for several years. Therefore, there is a chance that the latest Chevy Volt will end in California or Arizona.

However, if you are not based in Arizona or California, you may be seeing a different brand of Level 4 autonomous vehicles near you. At the moment, Uber had focused on a fleet of self-driving cars in Pittsburg, as an accident in San Francisco had forced the company to downgrade the tests a bit. Ford has partnered with Walmart to deliver food from a Fusion hybrid sedan in Miami, and by 2021, autonomous Ford taxis should drive.

There are several other companies that are planning to bring Tier 4 autonomous cars into American roads the next few years, including Nissan and Volkswagen. However, they are a bit late and have not announced in which cities they want to test their cars.

Where are the level 5 autonomous cars?

The Most Important Reason Why You Will not Do It If you have a Tier 5 self-driving car in your garage, it's simply because they do not exist yet. According to SAE standards, a Tier 5 autonomous vehicle must function like a human in novel locations and must be able to respond to wildlife dangers like a human.

But here's realistic. Level 5 autonomous cars must surpass man at every turn, and a savage act of God, before the legislature allows them on our roads. We need data that shows that a car controlled by a human being is inherently more dangerous than a computer-controlled car.

So what is to be done? For starters, manufacturers could send their safety reports to the US Department of Transportation. Until the DOT has a good collection of safety data, no laws will be passed. Understandably, not every company has enough data to submit annual reports to the DOT, and only Waymo and GM have managed to come out on top.

However, the biggest hurdle for autonomous car manufacturers is not the DOT, but the AI. Of course, the AI ​​will improve over time. Here's the catch, it has to get better to think of as a human, and developers have to think better than AI.

We built roads or highways for the use of humans, not robots. Therefore, our understanding of the "light" and "hard" parts of driving is completely subjective. As manufacturers focus on how KI can make the ride as smooth as possible by adjusting the suspension in real time (which is pretty cool), they ignore the fact that AI can be completely unreliable in some average real driving situations. 19659028] A woman with a yoga mat opening a door to a Waymo taxi ” width=”650″ height=”300″ src=”/pagespeed_static/1.JiBnMqyl6S.gif” onload=”pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);” onerror=”this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);”/>

Waymo

For example, think of the Tesla crashed into the back of a truck on the road in autopilot mode? This happened because the Tesla could not distinguish the shiny side of a truck from the sky. However, Tesla not only uses cameras but also radar (unlike competitors, Tesla does not use LiDAR). Before this wreck happened, the Tesla's radar systems discovered an obstacle that should have activated the brakes. However, Tesla has designed its radar system to ignore large horizontal objects, as most of the large horizontal objects you see on the highway are just traffic signs. As Tesla took the time to solve an obvious problem, they ignored how their solution could hamper AI's ability to make good decisions.

Manufacturers must also teach the subtle language of the way to the AI. You are constantly communicating with other drivers, whether you notice it or not. If another driver flashes his turn signals on a four-way stop, he indicates that you have priority. If you drive on the highway, other drivers will not let you in unless you use a bit of confidence and aggression. If an autonomous car does not know how to use subtle forms of communication on the road, it will never be reliable or safe. Of course, the best solution to this problem is to replace every car on the road with a self-driving car, but that will not happen for decades (at least).


Although you can not own a self-driving car Now you can get a taste of the future in a Tier 2 or 4 autonomous vehicle. These options are not yet available to all. So, if you're not an autonomous car lover who is less than lucky, you'll have to settle for photos from the Detroit Auto Show or CES 2019.
