I'm questioning the direction of the arrow in the diagram.

Not saying the first one posted is wrong, just want an explanation of why it is not the way I've revised it.

Also the negative pressure or vacuum of the Scion Xd end/behind is what "PULLS" Alan down, he is not pushed, right?

See the rolling vortex of air behind the Chevy Volt recently posted.
