If you follow the link in your link, you'll see that while new Postal Service trucks are $60,000, the Rivian vans START a $83,000†, and it's simply not possible for the driver of one of those vans to reach a mailbox from inside the vehicle, which is how vast majority of what the new Postal Services will be used.
Paying a 40% premium for less capability? That doesn't sound smart.
I was just saying that the vehicle is commercially available, not that it was a better option for the US Postal Service. But $83,000 is the retail price. Anyone buying in bulk will get them for significantly cheaper. The $60k for the NGDV is the discounted price for a bulk buy of 50,000, and it's for a mix of ICE and EVs. The ICE vehicles are significantly cheaper to manufacture, so the EV price is probably close to the Rivian's bulk price, and the Rivian has significantly greater capabilities.
According to you, some random tech bro CEO who hasn't delivered hundreds of letters a day for decades and is just looking at cost and going "hey, this isn't the cheapest option, it must be one of those darn government projects meant to subsidize those annoying poor people!"
