Waymo has started the final phase of fully driverless vehicle testing in Denver, Colorado [1, 2].

This phase serves as the critical bridge between internal development and commercial availability. By validating the technology in a complex urban environment, the company aims to ensure safety before the general public enters the vehicles.

During this current testing period, the autonomous vehicles are carrying Waymo employees as passengers [1, 3]. These ride-alongs allow the company to gather real-world data and monitor system performance in live traffic. Public access to the service remains on hold while these internal evaluations continue [1, 2].

The initiative is designed to validate the autonomous technology and prepare for a wider public rollout expected later this year [2]. This process follows a standard progression for the company, moving from mapped simulations to human-monitored drives, and finally to fully driverless operations.

Denver represents a strategic expansion for the company as it seeks to scale its ride-hailing footprint across the U.S. [2]. The company is focusing on how the vehicles handle the specific infrastructure and traffic patterns of the Colorado capital before opening the app to residents.

The transition to employee-only driverless tests indicates that Waymo has likely completed its primary mapping and safety-driver phases in Denver. This move signals a shift toward operational readiness, suggesting that the company believes its software can handle the city's specific road conditions without a human safety driver present. A successful rollout would further solidify the company's lead in the competitive autonomous ride-hailing market.
