I'm a little sad to see this because I'm moving northward to Seattle next month, I've lived in Portland proper for over 16 years, and Seattle doesn't have Waymo yet. Great timing lol.
Portland will probably be a great testing ground for them because generally speaking you have a lot of tech curious and tech averse people here living together. When we got electric scooters there were both tons of people using them and a lot of people throwing them in the Willamette. Pretty big artistic community that doesn't look kindly on AI right now. This has no real bearing on Waymo's success, but I'll be interested to see how they navigate the PR part of it.
