Yeah the Beginner Course too. It was great with the kei cars.
The Motorland track was the one with the hinky off-camber turn before the pit entrance. (Though I can't remember if that was on the reverse maybe?)
If you did the 1-make race in GT4 - in I think the Lupo, you would get messages that the AI Lupos would keep entering the pit by accident, after hitting that off-camber turn at a bad angle.
That just cracked me up. It was not a long race, and you'd just see the messages popping up that the AIs were entering the pits.
I remember having lots of fun there with kei cars & cars like the Eagle Talon, in Family cups.
