In Texas, driverless trucks are set to take over roads

Houston, United States―A giant 18-wheel transport truck is barreling down a multi-lane Texas highway, and there is no one behind the wheel.

The futuristic idea may seem surreal, but it is being tested in this vast southern US state, which has become the epicenter of a rapidly developing self-driving vehicle industry.

Before driverless trucks are allowed onto roads and highways, however, multiple tests must still be conducted to ensure they are safe.
Self-driving lorries are operated using radars, laser scanners, cameras and GPS antennas that communicate with piloting software.

“Each time we drive a mile or a kilometer in real life, we re-simulate a thousand more times on the computer by changing hundreds of parameters,” explains Pierre-François Le Faou, trucking partner development manager at Waymo, the self-driving unit at Google’s parent company Alphabet.

Waymo is building a logistics center in Dallas that will accommodate hundreds of autonomous semi-trailers. 

And it is by far not alone. Embark, a self-driving technology startup, operates an autonomous trucking lane  between Houston and San Antonio, while Aurora, co-founded by a former Waymo employee, will open three terminals and a new 635-mile route (1,000 kilometers) in Texas this year.

In a sign of how competitive the autonomous trucking industry is, none of the three companies agreed to show AFP one of its vehicles.

“I think that everybody who is in the autonomous trucking business is in Texas,” says Srikanth Saripalli, director at the Center for Autonomous Vehicles and Sensor Systems at Texas A&M University. “Even if they don’t advertise it.”

The companies didn’t land in Texas by chance. The state has the largest number of truck drivers and many qualified engineers, its sunny climate is great for the trucks’ sensors, and neighboring Mexico exports 85 percent of its goods to Texas by road.

Houston and Dallas are major freight hubs, and Texas’s sprawling distances are ideal for long-haul transport.

But most of all, local legislation is friendly toward driverless vehicles.

In 2018, Texas passed a law that essentially gave autonomous cars the same status as conventional vehicles.

“You need insurance and you need to follow the rules of the road, but other than that Texas does not impose any other regulations,” says Saripalli.

With the United States so vast and trucking such a vital part of its economy, companies see self-driving as a way to cut costs and reduce risk, since unlike with human drivers autonomous vehicles don’t get tired and don’t require mandatory breaks.

While it will take a person three days to drive a truck from Los Angeles to Dallas, a self-driving big rig will complete the journey in 24 hours, estimates Aurora. 

And it will be nearly twice as cheap. The per-mile cost would drop from $1.76 to $0.96 if the truck drives itself, according to Embark.
