Waymo, the self-driving unit of Google parent company Alphabet, has hit another milestone: 8 million miles driven on public roads. That translates into roughly 25,000 miles driven every day, which is light-years ahead of the company’s competitors and is the result of Google’s very early investment in self-driving technology.

The news was delivered by the company’s CEO John Krafcik on Friday at the National Governors Association in Santa Fe, New Mexico, in an interview with Nevada Gov. Brian Sandoval. Last November, Waymo announced it had driven 4 million miles on public roads, which means the company doubled that number in eight months.
