Amazon’s self-driving vehicle brand Zoox will soon hit the streets of Seattle following tests in Las Vegas and the Bay Area.

Zoox has been testing its vehicles for over four years, but every city is unique.

“Our goal isn’t to change mobility in a few states; we want to reimagine transportation for the whole world,” explains Zoox in its announcement. ”To do that, we have to prepare for unfamiliar roads and novel conditions.”
