Autonomous cars could end drowsy driving, but don’t hold your breath

Most drivers wouldn’t even consider driving while drunk, but few so much as pause before getting behind the wheel when they’re tired—even though drowsy driving can be just as dangerous as drunk driving.

According to the CDC, drowsy driving caused 72,000 crashes in 2013. These crashes resulted in 44,000 injuries and 800 deaths that year, though the CDC suggests these numbers could be low and the problem may be getting worse. In 2016, the U.S. Department of Transportation reported that traffic deaths were on the rise, a stark contrast to decades of lowering numbers. Drowsy driving almost certainly plays a part in this increase.

With all this in mind, it’s unsurprising that the National Highway Traffic Safety Administration is calling for a variety of approaches to reduce drowsy driving, including changes in legislation, education, and technology. The rise of smart and self-driving cars could help reduce the occurrence of drowsy driving accidents, making the roads safer for everyone, but don’t hold your breath.

Driverless roads offers hope for the distant future

It’s clear that self-driving cars are the future. Companies from Tesla to Uber to Google to just about every major car manufacturer are working on the technology. Audi and Google already have working vehicles, Tesla’s latest models have impressive autonomous features, and most other manufacturers hope to launch autonomous cars in 2020. Driverless technology is close enough that Congress recently passed legislation to move forward with the concept.

Driverless cars will change many things, but their potential to eliminate drowsy driving accidents is one of the most exciting. Most of these companies are developing fully autonomous vehicles. That means a person’s drowsiness will no longer pose a risk, as the car will be its own driver.  This will prove especially beneficial for professions like trucking, which requires long, late hours and plenty of time on the road—both significant risk factors for drowsy driving.

Autonomous cars offer a promising solution, but we cannot rely solely on the hope that we will one day have a completely driverless future to reduce the number of fatigue-related accidents. Many automakers are working on autonomous technology, but user adoption will still need to catch up even when driverless cars are more affordable and readily available.

Smart sensors detect drowsiness 

Although self-driving cars are perhaps one of the most obvious solutions to this problem, they aren’t the only answer. Before we see a fully autonomous future, we can expect to see a more widespread adoption of car technology that recognizes drowsy drivers. In fact, Mercedes-Benz already uses Attention Assist to guide drowsy drivers to nearby rest stops.

During the first several minutes of a drive, Mercedes’ Attention Assist takes note of over 70 parameters to understand driving behavior. As the drive continues, the technology monitors the driver’s steering to identify corrections that could indicate drowsiness. The system also takes into account factors like crosswinds and road smoothness for accuracy. If the system adds up all the factors and determines the driver is drowsy, it provides an alert encouraging the driver to stop for a rest. This is great news for current and aspiring Mercedes owners, but what about the rest of us?

Similar technologies that could impact other car manufacturers are in the works. For example, Panasonic is developing a system that measures a driver’s body temperature, blinking, and facial expressions to detect how tired they are. The system then adjusts the car’s temperature and lighting to perk up the driver. This technology could be in cars as early as next year, helping prevent thousands of drowsy driving accidents.

Chipmaker, Nvidia, is also in the process of developing a technology that could help reduce the number of drowsy drivers on the road. The company recently made headlines for their project to develop a product called Co-Pilot. The technology learns the behaviors of a driver and looks for deviations that could signal drowsiness. Changes in functions like the driver’s posture, blink rate, head position, and steering style trigger the system. When Co-Pilot senses something is amiss, the technology alerts the driver of the danger associated with continued operation of the vehicle. Co-Pilot is still under development, but it offers a promising outlook on the safety of future roads.

Until these baked-in technologies are available in more cars, wearables could help. The Steer bracelet offers a potential solution to drowsy driving. The technology monitors driver behavior and sends a “gentle” electric shock if it senses fatigue. Aside from the obvious caveat of essentially asking drivers to wear a shock collar around their wrists, this technology could be a solid option for long-haul drivers looking for an immediate solution that’s a bit more budget-friendly than a brand new Mercedes.

There’s plenty of other drowsiness-detecting technology in the works. In the future, detected drowsiness could signal the car to take over. Until then, these technologies will adjust the cabin to wake drivers up or urge them to pull over.

Our cars can’t save us quite yet

Automotive AI is advancing quickly, but we’re still several years out from achieving a widespread solution. For now, cars with advanced safety features like lane monitoring that can detect when you drift out of your lane and backup cameras that are available in most new cars could help drivers remain a little more alert. Technologies like Steer and other wearable devices could also help drivers who drive older models without the latest safety features. While such technologies aren’t a perfect for solution for drowsy driving, they can help combat some of the effects until we have an all-compassing solution.

Above all: Get some sleep, and drive safely.
