From the original press release:
> "Part of what makes Arizona an ideal place for Uber and other companies to test autonomous vehicle technology is that there are no special permits or licensing required," the ADOT release said. "In Arizona, autonomous vehicles have the same registration requirements as any other vehicle, and nothing in state law prevents testing autonomous vehicles."

{not an 80+ driver}
As a motorcyclist with a 45 minute commute, I'm on the cautious side when it comes to self-driving tech on the roads, but I have to say that anecdotally it's been fine so far. I'd be willing to bet I see ~10 Waymo vehicles a day. I've had plenty of issues with normal cars/drivers, have never had nor seen an issue with Waymo.
