In pics: Texas, the self-driving trucking industry's promised land

Several companies, including Aurora Innovation and TuSimple, plan to deploy fully driverless trucks on Texas' interstates next year, moving away from current testing that includes back-up safety drivers behind the wheel.

While some limited driverless tests with 18-wheelers have taken place in Arizona, a launch in Texas would mark the first commercial use. Alphabet's Waymo Via and box truck startup Gatik which counts Wal-Mart as a customer, are setting up hubs there in preparation.

Companies have poured billions of dollars into developing the technology they say will increase road safety and alleviate truck driver shortages. The self-driving truck industry in the U.S. is expected to rapidly grow over the next decade, with analysts estimating its size at between $250 billion and $400 billion by 2030.

Darran Anderson, director of innovation at the Texas Department of Transportation (TxDOT), said the state has decided to pursue a collaborative approach with the industry.

But safety advocates are worried.

"Rushing this technology to market using regular drivers as beta testers in real-world driving conditions puts potentially everyone at risk," said Ware Wendel, executive director of consumer advocate Texas Watch.

Texas in 2017 passed its autonomous vehicle bill permitting the testing and deployment of driverless vehicles without the need for special registration, data-sharing or additional insurance requirements. The law also prevents local cities from imposing additional requirements.

The industry is using the bill as a blueprint when lobbying other states about regulating self-driving vehicles, a Gatik executive and safety researchers said.

Safety proponents warn the companies are trying to pit states against each other by threatening to take jobs to more favorable regulatory environments.

The companies say safety is their highest priority, and testing on public roads allows them to fine-tune and scale their technology under real-world conditions.

Texas boasts some of the country's fastest-growing metropolitan areas as well as several entry ports from Mexico. It also sits in the middle of one of the busiest U.S. freight routes, Atlanta-Los Angeles, which carries more than 8,500 trucks daily, according to the U.S. DOT. Self-driving companies hope to automate many of those highways.

Property developer Hillwood's huge AllianceTexas logistics zone near Fort Worth, which includes a freight airport, rail yard and vast regional hubs of Amazon.com, FedEx and UPS, hopes to attract more AV trucking.

TuSimple and Gatik have hubs at the 27,000-acre complex. Hillwood is creating robotruck-friendly infrastructure by minimizing left turns that are more complex because they cut through traffic, installing 5G networks and building AV-specific warehouse docks, said Ian Kinne, Hillwood's logistics innovation director.

For trucking companies, Texas' collaborative regulatory regime explains much of its attraction.

"There are other states that have really great ports or connections, but they don't have the same regulatory environment that Texas has," said Aidan Ali-Sullivan, Waymo's state policy manager.

With federal AV regulation stalled for several years, it has been left to individual states to figure out policies.
