>but if they want to bring their car they need to ship it down This is why the helicopter flights are so popular. They're literally just flying across the border with the shortest possible thing that could be called a flight, because air travel is allowed. And they're getting their car (or more often, RV) towed across the border, because cross-border towing is also allowed. The shortest possible flight means the shortest possible tow.
