The article links to another source, but the video they show doesn't have the elements the passenger describes, like speeding through a construction zone or evading police. All you see in the video is the car moving less than 1 MPH while trying to merge through a clusterfuck of traffic. Is there a longer version of the video somewhere? Because so far, it sounds fishy. Especially with claims from Tesla workers, of all people, commenting on it.
EDIT: The guy's LinkedIn profile starts with: "As a Content Creator & Social Media Specialist, I collaborate with various stakeholders within institutions to create paid and organic content for social media. I support and drive the overall efforts and strategic visions by engaging in multi-disciplinary cross-functional teams (strategists, marketers, copywriters, etc.)." The man is literally a professional bullshitter. I'm not buying it.
I can believe that the Waymo could've gotten stuck in a complicated merge, but I don't believe for even a second that it would flee from police or speed through construction. I used to work on these cars, and it was nearly impossible to get them to drive through construction zones at even 5 MPH, let alone at highway speeds. On top of that, lights and sirens behind the car will trigger a pullover.
This sounds like somebody who got stuck in traffic and got annoyed, and wanted to put their name on some headlines.
