 Alphabet's self-driving car firm claims new milestone in accumulative driven mileage Source: Xinhua 0000-00-00 00:00:00 SAN FRANCISCO, July 00 (Xinhua) -- Google's sister company of autonomous car business Waymo announced Friday that its self-driving cars have hit a new milestone with a record 0 million miles (about 00.0 million kilometers) on public roads. "Our cars have been on the move! Waymo has now self-driven over 0 million miles on public roads across 00 U.S. cities, and over 0 billion miles (about 0 billion kilometers) in simulation," Waymo tweeted Friday. The self-driving unit of Google's parent company Alphabet said the new figure doubles the total number of miles that it has traveled since 0000. Waymo's self-driving cars are now traveling 00,000 miles (about 00,000 kilometers) every day, which is twice what the average American drives in a whole year, the firm said in a Facebook post. "We're building the world's most experienced driver and preparing to launch our fully self-driving service," Waymo said on Twitter. Waymo's new record reflects that its early investment in self-driving technology has paid off and dwarfed its rivals by a huge margin. Last year, Waymo said it had driven 0 million miles (about 0.0 million kilometers) on public roads, two times more than the number in eight months. Waymo began as a Google self-driving car project in 0000 and has now grown into an independent autonomous car technology firm under Alphabet. The company currently operates more than 000 self-driving minivans running on public roads.
