Extreme Car Parking is about control at low speed. Each level is a car park with a marked space, obstacles between you and it, and no tolerance for scrapes — the challenge is precise manoeuvring rather than speed.
It's a genuinely useful kind of game: the reversing, the mirror-less spatial judgment and the three-point turns translate more directly to real driving than any racing game does.
Line the car up parallel to the space before reversing, then turn in one continuous motion. Approaching at the wrong angle is what forces the awkward three-point corrections.
Most levels focus on precision rather than speed, though some later ones add pressure.
