Waymo, a self-autonomous vehicle company, has begun testing its driverless fleet in Austin, Phoenix, San Francisco, and Los Angeles. Currently, Waymo operates in cities such as Austin and Phoenix, with more cities in the works. The company is working to make its fleet more assertive and more cautious. The car is constantly monitoring what's happening, monitoring its route and arrival time on a screen, and can detect if something is left behind. However, there are flaws in the car's submissive functionality, which have led to major disruptions, which Waymo acknowledges.
