How about a personalized travel map? You could get a map of the United States or the country they most frequently travel in, and have it framed with their names and wedding date. Then, they can mark all the places they've been together and plan for future road trips. Another idea could be a gift basket filled with items to make their road trips more comfortable, such as a travel pillow, blanket, snacks, and a car phone charger. You could even include a book of scenic drives or road trip games to add to the fun.
Or you can get her/him a star map with the date of the wedding.
