In November 2017, Waymo announced that it had begun testing driverless cars without a safety driver in the driver position. In October 2018, Waymo announced that its test vehicles had traveled in automated mode for over 10,000,000 miles (16,000,000 km), increasing by about 1,000,000 miles (1,600,000 kilometres) per month.

In Arizona, Waymo has fully autonomous taxi service you can use right now. https://waymo.com/apply/

Is that a lot of hype? Maybe.
