Have you tried a booster seat, he'll be elevated, able to see out of the window. His anxiety may be from being confined in back seat, not able to see anything but the back of the seats. It's worth a shot if you haven't tried one. A small investment of maybe $25./$30. Pet Smart, Pet supplies , if it doesn't work out can be returned.
