By Heather Somerville and Alexandria Sage SAN FRANCISCO (Reuters) – Uber Technologies Inc on Thursday removed its self-driving test cars from California and put them on trucks bound for Arizona, shuttering the autonomous vehicle project in its home state after a week-long battle with regulators. The California Department of Motor Vehicles on Wednesday revoked the registration of 16 cars in Uber's self-driving fleet, which the regulator said lacked the proper permits. Arizona, however, does not require any special permits for self-driving cars, according to the state Department of Transportation.
