Uber pulls self-driving cars from California roads

Uber pulled its self-driving cars from California roads on Wednesday after state regulators moved to revoke their registrations, officials said. The decision came after a week of talks between the ride-sharing company and state regulators failed. The DMV said the registrations for the vehicles were improperly issued for because they were not properly marked as test vehicles. It invited Uber to seek a permit so their vehicles could operate legally in California -- an offer the company said it did not plan to accept. The controversy started when Uber launched the service in its hometown of San Francisco.
