Huey still gets car sick occasionally, but it is usually on twisty turny mountain roads. The pukage decreased dramatically when I got him a car seat where he can see out the window. It also helps to have the a/c blowing where he can put his face in it. Many times he just curls up in his secure car seat and goes to sleep, but he is a terrible back seat driver and jumps up to look out the window every time you turn a sharp corner or brake harder than he thinks you should.
