Recently, the California Department of Motor Vehicles (DMV) has confirmed to Mac Reports that Apple has 55 vehicles on the road with 83 drivers.
It seems that Apple grows its fleet of self-driving test cars. That gives it the second-largest fleet in the United States of America, ahead of Waymo's 51 cars, but still well behind GM Cruise, which boasts 104.
Each participant in this self-driving auto race must have a safety driver in the vehicle during testing. Apple actually has more self-driving cars in testing than self-driving pioneers such as Waymo (51) and Tesla (39), as well as big automotive companies like BMW (12), Toyota (11), and Mercedes Benz (5). However, those numbers may be somewhat misleading, since other companies are testing their self-driving fleet in other parts of the U.S.as well.
In April 2017, Apple received its first official permit from the California DMV to operate self-driving test cars on its roads.
Code-named "Project Titan", Apple's self-driving programme's fleet is reportedly made up of Lexus RX450h SUVs, each of which is fitted with huge racks of LIDAR and radar sensors as well as cameras. Apple's self-driving auto program is still a mystery, but it appears to be centered around testing and collecting data for self-driving software, instead of a complete vehicle.
As of now, the DMV has not issued any permits for complete driverless testing because for that to happen, companies must have to have a pre-testing of the vehicles in controlled conditions.
