Self-driving cars have been on our minds for a while now, and manufacturers seem to be making progress every day. But when will you have a self-driving car in your driveway?
Well, the answer is a bit complicated. To answer it, we need to understand where we are with self-driving cars right now, and what steps we need to take to make fully autonomous cars a reality in the future.
When is a Car Fully Autonomous?
According to SAE International standards, autonomous cars are rated with a “level” on a scale from 0 to 5. Level 0 cars have no autonomy and must be controlled by a human at all times. Level 5 cars are fully autonomous and don’t require any help from a human to operate.

The car that you’re driving right now is, more than likely, a Level 1 autonomous vehicle. It has cruise control features, and it might even have a backup camera. But there’s a chance that you’re driving a Level 2 or Level 3 semi-autonomous car, like a Tesla, a Cadillac CT6, a Mercedes-Benz E-Class, or a Volvo S90. These cars have features like Auto Pilot or Super Cruise, which allow you to take your hands off the wheel while your car maintains a steady speed and changes lanes.
Okay, glorified cruise control is super cool, but you’re trying to buy a fully self-driving car. Are there any Level 4 or Level 5 autonomous cars on the market? The answer is a resounding “no,” but you could find yourself in a genuine self-driving car very soon.

۲۰۱۹ is the Year of Level 4 Autonomous Cars
We haven’t talked about Level 4 autonomous vehicles yet, but they’re an important step in the journey to self driving cars. The dividing line between Level 4 and Level 5 autonomous cars is, essentially, flexibility. While Level 5 autonomous cars can traverse anywhere on a whim and safely maneuver through novel locations, Level 4 cars are stuck in predetermined areas, like a city or a state. Level 4 cars are also fed roadmaps and travel data that make everything super easy and safe. While Level 5 cars are comparable to hyper-aware human drivers, Level 4 cars are comparable to a near-blind person walking the streets of a familiar city.
That’s why Level 4 autonomous cars are being built specifically for driverless ride-sharing and delivery services, not for the retail car market. These cars run on a predetermined track, but they’re capable of maneuvering between lanes and avoiding collisions with cars or pedestrians. They’re reliable, safe, and good for collecting data that will be useful for Level 5 cars in the future. Manufacturers are already using Level 4 autonomous cars in some cities, and there’s a decent chance that you’ve seen (or been inside of) a Level 4 autonomous car.
Waymo
Waymo, the self-driving car company that was founded by Google, is one of the forerunners of Level 4 self-driving cars. The company has been working on autonomous cars for almost a decade, and Waymo vehicles are currently used for ride sharing (by a select group of people) in Chandler, Arizona and San Francisco, California. Residents of the Metro Phoenix area that want free rides in a Waymo autonomous taxi can sign up for an Early Rider program right now, but spaces are limited, so don’t spend too much time thinking.
