Today, Waymo announced its own expansion — minus the puerile humor. It’s just a bigger map with more customers for the Alphabet-owned company’s budding robotaxi business. And more pressure on Tesla to drop the dick jokes and get serious about autonomous driving.

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

Alphabet's Waymo is expanding its service in Austin, Texas, to 90 square miles from 37 square miles earlier, the software giant's self-driving unit said on Thursday, seeking to protect its top position in the city from rivals such as Tesla.
