(CNN) - Right now, there's a shortage of truck drivers in the US and worldwide, exacerbated by the e-commerce boom brought on by the pandemic.
One solution to the problem is autonomous trucks, and several companies are in a race to be the first to launch one. Among them is San Diego-based TuSimple.
Founded in 2015, TuSimple has completed about 2 million miles of road tests with its 70 prototype trucks across the US, China and Europe. Although these are simply commercially available trucks retrofitted with its technology, TuSimple has deals in place with two of the world's largest truck manufacturers -- Navistar in the US and Traton, Volkswagen's trucking business, in Europe -- to design and build fully autonomous models, which it hopes to launch by 2024.
TuSimple's latest road test involved hauling fresh produce 951 miles, from Nogales, Arizona to Oklahoma City. The pickup and the dropoff were handled by a human driver, but for the bulk of the route -- from Tucson to Dallas -- the truck drove itself.
"Today, because the system is not fully ready, we have a safety driver and a safety engineer on board at all times when we're testing, but we drove in full autonomy: the driver wasn't touching the wheel," said Cheng Lu, TuSimple's president and CEO. The journey was completed in 14 hours versus the usual 24 with a human driver, mostly because a truck doesn't need to sleep. "In the US, a driver can only work 11 hours a day.
We simply had a handoff when our first pair of drivers had to stop because they reached their 11 hours of operation," said Lu. That, of course, negates the advantage of an autonomous system, so the idea is that once TuSimple's trucks hit the market, there will be no need to have anyone onboard.
Unlike self-driving cars, which are a still a way from being commercially available, TuSimple trucks won't be required to operate in bustling city traffic, but only on stretches of highway that have been thoroughly mapped via the company's own software.
"We collect data from the roads, and we create this very detailed, high definition map of each route. That adds another layer of safety for the vehicles," said Lu. As a result, TuSimple's trucks will only be able to self-drive along these pre-mapped trade corridors, which Lu calls "virtual railroads," and nowhere else.
According to the company, in the US 80% of goods travel through just 10% of the nation's trade corridors, so even selective mapping allows for capturing a large portion of the business. TuSimple is currently mapping routes between Arizona and Texas, and plans to have mapped routes across the nation by 2024.
Its plans are dependent on state legislation, however, because currently some states do not allow for testing of autonomous trucks on public roads.
The technology will add about $50,000 to the cost of a truck, making the final price roughly $200,000. According to Lu, that's still cheaper than paying for a human driver.
"If you take $50,000 and divide it by 1 million miles, the average lifespan of a truck, that means you're adding five cents per mile. But you're saving the cost of a human driver, which based on average US wages is about $80,000 to $120,000 per year -- or 80 cents to $1.20 per mile. Today, the direct labor cost is about 50% of the cost of operating a truck," he said.
That doesn't mean driverless trucks will take away jobs, according to Lu. By focusing on the "middle mile," rather than on the pickup and delivery of the goods, TuSimple believes it can create new freight capacity without creating new demand for drivers, while at the same time protecting existing jobs. "A UPS driver is dropping off 200 packages a day -- that's not what autonomy is meant for. We believe that every driver will be able to retire as a driver, even if they enter the workforce today," said Lu.
