She stands on it, kicks a few times, flies out the back door of the semi, and onto the hood of a Pontiac that was following them much too closely. Its windshield makes a nice surface to bank off of, and she gets her direction neatly reversed by the time she hits the pavement. The owner of the Pontiac is honking self-righteously, but there's no way he can chase her down because traffic is totally stopped, Y.T. is the only thing for miles around that is actually capable of movement. Which is the whole point of Kouriers in the first place.
