Alphabet’s Waymo probably operates the most successful autonomous fleet in North America right now. While we can debate its technical prowess versus its rivals forever, it’s still one of the only companies offering a commercial taxi service using autonomous vehicles in North America. It also has an enviable safety record.

The company has also worked on adapting the technology for Class 8 trucks, testing such units previously in California, Atlanta, and Arizona. Recently, the company tweeted that self-driving semis would soon return for more testing in Phoenix — where it runs its Pacifica-based early rider program — as the company places a renewed emphasis on their development.
