I've reviewed the brand new training for First Responders that Aurora dropped last week. You can view them at https://aurora.tech/first-responders. Here is the breakdown.

SUMMARY: I am not sure why it took until 2026 for any company to publicly release a training course like this one. Maybe the prevailing mindset has always been, 'well why would a driverless truck ever need to interact with the Police!?' to which I would answer, 'no one is above the law.' Yes, these trucks will never speed, but something could happen that may (God-forbid) injure or kill a human being. And odds are, our nation's fine First Responders will be first on the scene. The fact that this training was even made is a small miracle, for no other company even bothered.
PROS:
Short Modules, about 5min each. Content is super-dense and can be revisited easily.
CONS:
Cannot view in full screen, closed captioning does not work. There could be a lower barrier to entry: One must fill out a webform and give one's email address to access all the modules. Change the reference from "meters" to be something that every first responder (and truck driver for that matter) can better relate to; for example, instead of "1000 meters" say "it can see 10 football fields ahead."
CONCLUSIONS:
I first heard of this at the SAE-GI Conference in DC, where panel G109 discussed this at length. Thanks to FedEx, Aurora, NHTSA & SAE for putting this on. You can see the Aurora trucks live in action almost anytime on their live stream at https://youtube.com/@AuroraDriver/streams
