Equinox:

When the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth's equator.

Most of The Cars and Characters Represent Something in Space.

The Guy on the bicycle = The Earth.

The Cars at 1:50 are the Stars.

The White Car at About 4:10 = The Moon.

(notice how it dissappears like the moon cycle)

Finally the car at 7:25 is the Sun.

When The Earth Turns at 7:31 is when there is a Vernal Equinox.
