Road tests, city drives and racing in 3D. This is a game. It is not affiliated with any DMV or driving school and does not issue a license. ■ ROAD TEST (CITY) LEARNER'S PERMIT, CLASS C and ADVANCED: three scored routes each with live traffic, a spoken examiner and shareable pass certificates. ■ ROAD DRILLS Generated US road scenes explain critical errors and let you retry. Share a DRILL CLIP. HARBOR uses OpenStreetMap routes with fictional names. ■ HEADING TO JAPAN? Before a trip or move to Japan, practice keeping left in a right-hand-drive school car on a driving-school course and in MACHI, a Fukuoka-style town with Japanese signs, buses and level crossings. Take a provisional-license test (70 of 100 points to pass) with an English or Japanese examiner. Nine lessons come with the Driving Test plan. A game for getting used to the feel, not driving instruction or legal advice. ■ RACE THE CAR YOU PAINTED SHORT, LONG, GYMKHANA and RIDGEWAY 2K. Time attack, supported CPU races, ghosts and Game Center rankings. Climb from Class A to International. ■ QUICK MATCH Match with a random driver online: two people, approved names or a generated fallback, stock paint and no prizes. SHORT and LONG add four CPU drivers; other venues add none. One entry a day is free (resets 00:00 UTC); Multiplayer Host or All Access makes it unlimited. ■ SOLO CAR TAG Free offline CITY/MACHI/GYMKHANA Tag: you and up to 7 CPUs. CPUs cycle your car's shuffled class pool; keep yours. Caught runners become chasers. Escape earns 300 points plus seconds near opponents; catches/assists score. See overall rankings and winning TEAM MVP. Nets mark confirmed catches. Results and match videos name cars to help you choose. ■ CAR TAG & PRIVATE ROOMS Three-minute car Tag with a 10-second head start. Stop and repaint to hide. Race or Tag: 2–8 on Wi-Fi, 2–4 in Internet rooms by code. Host one game/UTC day per Apple account free across both, separate from Quick Match; guests join free. ■ PAINT EVERY CAR Free-hand paint with four brushes, zoom, undo and a 3D preview. Designs pass an online check before racing. ■ TWO TOWNS CITY: US-style streets, a freight train, car wash and parking garage. MACHI: Japanese streets and the hillside suburb of IKENODAI. ■ GARAGE 20 cars (8 added), all with refreshed designs, 148 parts and service items. Automatic or clutchless sequential shifting, DRIVER camera with mirrors, controller support, race digest videos. ■ INCLUDED, AND WHAT NEEDS A PLAN - Free drive, solo and CPU races, painting, joining a friend's room: included - Every day: one driving test (US and Japan combined, resets 00:00 UTC), one Road Drills episode, one online paint check, one Quick Match - Unlimited tests and Road Drills plus the nine Japanese lessons: Driving Test plan - Unlimited paint checks: Unlimited Paint plan - Unlimited private-room hosting and Quick Match: Multiplayer Host or All Access - All Access: every plan above plus Premium Driver Portraits - Premium Driver Portraits (8 portraits plus your approved photo): one-time ■ SUBSCRIPTIONS Driving Test (1 month, Family Sharing supported), Unlimited Paint, Multiplayer Host (1 month each) and All Access (1 month or 1 year), auto-renewing, in one group: one active plan at a time.
