Khosrowshahi said, “When we get back on the road, we have to be absolutely satisfied we’re getting back on the road it in the safest manner possible.” Further, he added, ‘We’re having conversations with Waymo about putting their cars on our network. If something happens, great. If not, we can live with that, too.”

Uber, the ride-hailing service temporarily halted its self-driving operations in all cities after one of its self-driving cars was involved in Arizona fatal crash in April.

The agreement between two ride-hailing services would represent a dramatic shift, the self-driving car unit of Google parent Alphabet. Previously, both are locked in one of the highest profile court battles in Silicon Valley history.

After four days of testimony, two companies announced a settlement in which Waymo was awarded 0.34 percent of Uber’s equity, even Uber agreed to not incorporate Waymo’s confidential information into software as well as hardware used in its autonomous cars.

Yet, Waymo did not comment on this, however, it proceeded with plans to operate without Uber’s help. Moreover, the company plans to roll out an app-based service. The ride giant also has a partnership with Lyft Inc.
