Waymo needs some help, according to an email message the self-driving developer sent to residents of Washington, DC, on Thursday. “We are nearly ready to provide public Waymo rides to everyone in DC,” says an email sent to those who have signed up for Waymo’s DC service. Other US cities with Waymo service, including ones in California, Florida, and Texas, already had those rules in place before the company entered their markets. Like self-driving tech developers, those companies wanted to launch their new services in places where the rules didn’t align with their business ambitions. Three other companies, including Nuro and Amazon-owned Zoox, have permits to test self-driving tech in Washington, DC.
