USPS Inspector General asked to investigate agency’s decision favoring gas delivery vans over EVs
A group of U.S. lawmakers in the House Oversight Committee sent a letter to the U.S. Postal Service (USPS) Inspector General (IG), requesting an investigation into the agency’s order for Next Generation Delivery Vehicles (NGDV).
In a letter dated Monday, March 14, Democrats in the House Oversight Committee asked IG Tammy L. Whitcomb to investigate the Postal Service’s compliance with the National Environmental Policy Act (NEPA). They questioned if the USPS complied with NEPA’s requirements for environmental reviews before finalizing its NGDV contract.
“We write to request that the Postal Service Office of Inspector General (OIG) initiate an investigation into the Postal Service’s compliance with the National Environmental Policy Act, particularly the filing of the Environmental Impact Statement (EIS) for the Next Generation Delivery Vehicle,” wrote the Members.
“The Environmental Protection Agency, the White House Council for Environmental Quality and numerous environmental stakeholders have raised concerns that the Postal Service did not meet its NEPA obligations during its contracting process for the NGDV. These significant concerns warrant an investigation by the OIG.”
Background
The USPS received some criticism from the Biden Administration after it announced plans to spend up to $11.3 billion on as many as 165,000 gas-powered NGDVs. The Biden Administration urged the Postal Service to reconsider its plans to buy mostly internal combustion engine (ICE) delivery vehicles to upgrade its fleet.
The USPS fleet makes up a third of the U.S. government fleet. President Biden ordered all federal agencies to phase out the purchase of gasoline-powered vehicles. Even though the Postal Service is an independent agency, its fleet’s transition to electric vehicles would symbolize the current administration’s determination to move away from fossil fuels.
After receiving some pushback from the Biden Administration about its NGDV plans, the Postal Service issued a statement on February 6, announcing its plans to submit an initial order for 5,000 electric delivery vans. The agency also shared its goals to achieve 70% fleet electrification within the decade.
The Issue
The Environmental Protection Agency (EPA), the White House Council for Environmental Quality (CEQ), and other environmental stakeholders are concerned that the Postal Service did not meet NEPA obligations when it announced a 10-year contract with Oshkosh to manufacture fossil fuel-powered NGDVs.
The EPA pointed out that critical features in the contract were not disclosed in the Postal Service’s final review or Environmental Impact Statement (EIS) for the NGDV program. The CEQ observed that the agency’s final review was “flawed in some ways that cannot be so easily remedied.”
The New York Times discovered some evidence that supported the CEQ’s claims. The Postal Service estimated that the NGDVs would get 29.9 miles per gallon in its review. However, the EPA found that the vehicles would only get 14.7 miles per gallon or even less if air conditioning was factored into the equation.
The Postal Service’s (Current) Stance
USPS published a 340-page Final Environmental Impact Statement (FEIS) under the NEPA process on January 7, 2022. The Postal Service later completed a record of decision (ROD), which featured the agency’s response to feedback from the EPA on the potential environmental impact of the NGDV program.
In its ROD, the Postal Service outlines its decision to purchase and deploy 50,000 to 165,000 NGDVs over the next ten years. It details that the NGDV fleet will be a mix of ICE and battery electric vehicle (BEV) delivery vans. All-electric NGDVs will make up at least 10% of the fleet. The Postal Service determined that ICE NGDVs were the “most achievable” alternative to replacing its existing fleet rather than BEV NGDV, given its financial condition.
“…BEV NGDV(s) ha(ve) a significantly higher total cost of ownership than the ICE NGDV, which is why the Preferred Alternative being implemented does not commit to more than 10 percent BEV NGDV. Finally, the Postal Service notes that the Preferred Alternative as implemented contains the flexibility to significantly increase the percentage of BEV NGDV should additional funding become available from any source,” stated the USPS in its latest ROD.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.
