Uber is expanding its AWS contract to run more of its ride-sharing features on Amazon's chips. This is a thumb-of-the nose at Oracle and Google.

Kalanick's existing ghost kitchen company CloudKitchens will be rolled into Atoms, which also wants to get into mining and transport.

The launch comes just two years after a major reboot at Hyundai-owned Motional. The service will start with a safety monitor, which Motional hopes to remove by year's end.
