Waymo and Tesla ramp up robotaxi efforts, signaling a major shift in urban mobility and the future of autonomous transportation.

Alphabet's Waymo robotaxis have driven more than 100 million miles without a human behind the wheel, doubling the mileage in about six months, a top company official said, as it speeds up deployment in U.

The Alphabet-owned autonomous ride-hailing service now covers neighborhoods like Crestview, Windsor Park, and The Domain.
