Uber's self-driving Volvo SUVs are shipped off to Arizona from San Francisco on Dec. 22 (Uber)[/caption]rnrnUber packed up its fleet of self-driving Volvo XC90 SUVs from its home city of San Francisco on Thursday and shipped them to Arizona following a puzzling standoff with California over a requirement that the ride-hailing giant get a $150 permit before testing the high-tech vehicles on public roads.rnrnSeeing an opportunity to capitalize on the matter, Arizona Governor Doug Ducey welcomed the ride-hailing company to his state on Thursday, saying in a statement that "California may not want you, but we do."rnrn“Our cars departed for Arizona this morning by truck," Uber said in a statement.
