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

By Trevor Mogg Published May 31, 2019

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.

Toyota unveils 2026 bZ: A smarter, longer-range electric SUV

toyota bz improved bz4x 2026 0007 1500x1125

Toyota is back in the electric SUV game with the 2026 bZ, a major refresh of its bZ4X that finally delivers on two of the biggest demands from EV drivers: more range and faster charging.
The headline news is the improved driving range. Toyota now estimates up to 314 miles on a single charge for the front-wheel-drive model with the larger 74.7-kWh battery—about 60 miles more than the outgoing bZ4X. All-wheel-drive variants also get a boost, with up to 288 miles of range depending on trim.
Charging speeds haven’t increased in terms of raw kilowatts (still capped at 150 kW for DC fast charging), but Toyota has significantly improved how long peak speeds are sustained. With preconditioning enabled—especially helpful in colder weather—the new bZ can charge from 10% to 80% in about 30 minutes. Also new: Plug and Charge support for automatic payment at compatible stations and full adoption of the North American Charging Standard (NACS), meaning access to Tesla Superchargers will be standard by 2026.
Under the hood, or rather the floor, Toyota has swapped in higher-performance silicon carbide components to improve efficiency and power delivery. The AWD version now produces up to 338 horsepower and sprints from 0–60 mph in a brisk 4.9 seconds.
Toyota didn’t stop at just the powertrain. The exterior has been cleaned up, with body-colored wheel arches replacing the black cladding, and a sleeker front fascia. Inside, a larger 14-inch touchscreen now houses climate controls, giving the dash a more refined and less cluttered appearance. There’s also more usable storage thanks to a redesigned center console.
With the 2026 bZ, Toyota seems to be responding directly to critiques of the bZ4X. It’s faster, more efficient, and more driver-friendly—finally bringing Toyota’s EV efforts up to speed.

Cheaper EVs ahead? GM and LG say new battery cells are the key

2025 Chevrolet Equinox EV front quarter view.

General Motors and LG Energy Solution have announced a new phase in their ongoing partnership: developing a new battery cell chemistry that could significantly lower the cost of electric vehicles. The joint effort centers on lithium manganese iron phosphate (LMFP) battery cells, a variation of lithium iron phosphate (LFP) that’s gaining popularity for being more affordable and less reliant on expensive materials like nickel and cobalt.

This is a big deal because battery costs are still the single largest expense in producing EVs. According to GM and industry experts, LMFP cells could help bring the cost of electric vehicles close to — or even on par with — gas-powered cars. The goal? Making EVs accessible to a broader range of drivers without sacrificing range or performance.

Waymo recalled 1,200 robotaxis following collisions with road barriers

Waymo Jaguar I-Pace

Waymo’s autonomous-car technology has made great advances over the years to the point where it’s now allowed to offer paid robotaxi rides in select locations in the U.S.

But the development of the technology is ongoing, and the robotaxi rides continue to gather valuable data for Waymo engineers to pore over as they further refine the driverless system to make it as reliable and efficient as possible. Which is why glitches will sometimes occur.
