Toy vehicle track

A toy vehicle kit comprising:

• a first track piece including:
• a first pathway bounded by first opposing sidewalls and extending from a first end to a second end;
• a first male connector disposed at the first end of the first pathway, the first male connector including a first male main body with a recess formed therein to provide a first inset laterally bounded by surfaces that are elevationally aligned with the first pathway, such that the first inset and the surfaces laterally span a width between the first opposing sidewalls, and the first male connector also including a first protrusion extending elevationally away from the first inset towards, but not above, the first pathway;
• and a first female connector disposed at the second end of the first pathway, wherein the first male connector is separated from the first female connector by a first coupler span length that is a first increment of a base unit;
• and
• a second track piece including:
• a second pathway bounded by second opposing sidewalls and extending from a third end to a fourth end;
• a second male connector disposed at the third end of the second pathway, the second male connector including a second male main body with a second inset and a second protrusion extending elevationally away from the second inset towards, but not above, the second pathway;
• and a second female connector disposed at the fourth end of the second pathway, wherein the first male connector and the second male connector have matching configurations, the first female connector and the second female connector have matching configurations, and the second male connector is separated from the second female connector by a second coupler span length that is a second increment of the base unit, such that connecting the first track piece to the second track piece via a male-female coupling places uncoupled connectors along an x-y grid with grid increments of the base unit.
