USPS taps self-driving big rigs to move mail between cities

Add as a preferred source on Google

The United States Postal Service (USPS) is exploring the idea of transporting mail across the country using self-driving trucks.

The USPS has partnered with autonomous-truck company TuSimple for trial deliveries between its distribution centers in Phoenix, Arizona, and Dallas, Texas — a distance of around 1,000 miles.

Five round trips will take place across a period of two weeks, each one covering a distance of around 1,800 miles. And don’t be concerned if you find yourself tootling along the I-10, I-20, or I-30 during the trial and notice one of TuSimple’s autonomous trucks bearing down on you — the company is sending them out with both a safety engineer and a back-up driver to monitor performance and generally keep an eye on everything.

The USPS and TuSimple will operate the self-driving trucks for 22 hours at a time, which means overnight drives will also form part of the testing as they rumble along roads in three states.

“It is exciting to think that before many people will ride in a robo-taxi, their mail and packages may be carried in a self-driving truck,” TuSimple founder and president Dr. Xiaodi Hou said in a release. “Performing for the USPS on this pilot in this particular commercial corridor gives us specific use cases to help us validate our system, and expedite the technological development and commercialization progress.”

With the American Trucking Association citing a possible driver shortage of 175,000 by 2024, it’s easy to see why an increasing number of companies are exploring autonomous technology as a possible solution for moving freight across the country. The USPS said that such a system could also help it to reduce fuel costs, improve truck safety on the road, and boost its fleet utilization rate through longer hours of operation.

TuSimple was founded in 2015 and has bases in San Diego and Beijing. The company is working on the development of a Level 4 autonomous truck for commercial use. At the start of this year, it had 11 autonomous trucks performing test drives on Arizona roads, with a number of companies paying it to move their cargo during those trips.

BYD Seal 06 Budget EV at a Charging station

China's affordable EV market is getting ridiculously good in terms of value. Barely a day after Volkswagen opened preorders for its $17,175 ID. Era 5S plug-in hybrid, BYD has launched the 2027 Seal 06 with prices starting even lower.

The DM-i plug-in hybrid begins at 99,900 yuan, or around $14,700, while the fully electric Seal 06 starts at 109,900 yuan, roughly $16,100. In comparison, America’s cheapest EV, the 2027 Chevrolet Bolt, starts at $28,995. That makes the Bolt almost $13,000 more expensive than the entry-level Seal 06 EV.

Volkswagen ID. Era 5S Featured

Volkswagen's latest hybrid car is impressive on paper, but the real shocker is its price tag. SAIC Volkswagen has opened preorders for the ID. Era 5S in China with a limited-time starting price of 115,900 yuan, or roughly $17,175. Its regular Pure trim costs around $17,770, while even the range-topping Max comes in at just $22,215.

To put that into perspective, Chevrolet lists the 2027 Bolt at an MSRP of $28,995, making it America’s cheapest EV. Nissan’s 2026 Leaf starts at $29,990 before destination charges. So the cheapest Bolt is around $11,820 above Volkswagen’s introductory ID. Era 5S price.
