Waymo continues to expand the pool of locations where it’s testing its autonomous vehicle tech, and the latest destination is metro Atlanta. The former Google self-driving car company revealed the news on Twitter, noting that it’s expanding considerably its geographic testing footprint now that it’s got fully driverless test vehicles on the road in Phoenix.

Its test cars in cities outside of Arizona still have safety drivers at the wheel, but the more places it can get its Pacificas with autonomous tech on roads, the better for building an autonomous driving ‘brain’ that can handle anything it encounters. Atlanta has some specific challenges, including bad traffic (commute and traffic issues are ranked among the worst locations in the U.S.) and one of the more dense greater metro areas in the U.S., and temperatures that regularly reach a humid 80+ degrees Fahrenheit.
