In Capsule Corp, a yellow hovercar can be found to the left directly after entering the building. A scientist working on the hovercar reveals that it's a prototype model that he predicts will be a "huge hit" when it's finished and released. According to the game's official strategy guide, this hovercar is the same one used by Goku and his driving instructor in the "Dragon Ball Z" filler episode "Goku's Ordeal", where Goku and Piccolo are forced by Chi-Chi to take driving lessons.
