Last April, Apple was granted a permit to test its autonomous vehicle technology by the state of California and since then, the company has expanded its test fleet from three vehicles to 27, Bloomberg reports. The California Department of Motor Vehicles said that Apple had registered 24 Lexus RX450h SUVs between last July and this month. While initially aiming to develop its own autonomous vehicle, Apple later decided to switch gears and design a self-driving system that could be incorporated into other vehicles. And we've seen glimpses of that technology in recent months. A patent application, a presentation from Apple AI Research Director Ruslan Salakhutdinov and a research paper have all pulled back parts of the curtain Apple's technology development usually hides behind. And a closeup look from Voyage cofounder MacCallister Higgins gave us a bit of a visual.
