Apple has leased a “small fleet” of cars from Hertz to test its self-driving car technology, Bloomberg reports. In the latest round of filings with the California DMV, Apple is shown to be leasing more of the Lexus RX450h models that it was originally reported to be using to test its systems, all coming from Hertz’s Donlen fleet-management unit. The deal mirrors a much larger agreement between Alphabet and Avis for a similar arrangement, and Hertz’s stock jumped 18 percent on the news of its relationship with Apple. Neither Hertz nor Apple commented on the report, but a person familiar with Apple’s project said the company has been testing a half-dozen self-driving vehicles on public roads near San Francisco for more than a year.
