Vehicles
The vehicles are the main inhabitants of the world of Cars and Planes, set on a world populated entirely by anthropomorphic vehicles and no humans.
Biology
Vehicles come in different shapes, sizes, colors, makes, and models. Many have their eyes located on their windshield (as opposed to being on their headlights, which serve as their cheekbones instead, unlike most cartoon cars like the Chevron cars, though there is one exception to this rule). The vehicles windows are all opaque and gray, so no one knows what's inside them, and it's implied that they may not be hollow (though some concept art imply the presence of animal-like organs inside them). None of their doors ever open, convertibles always have their roofs up, vehicles without a roof in real life (such as Francesco Bernoulli) are given on in this world, and vehicles with asymmetrical cockpits (such as Topper Deckington III) in real life have perfectly symmetrical cockpits in the same world. Whenever a car blushes, his/her headlights start turning on at the wrong time, or shine brighter if they were already on. Cars typically have four wheels, but some vehicles have fewer like three, or more like six.
Cars do not wear clothing, but some appear to have headgear of some kind (such as trucks having wind deflectors resembling trucker caps). Most car names either be based on the type of car they're based on (Sally Carrera, Doc Hudson, etc.), a car-related pun (Darrell Cartrip, Nigel Gearsley, etc.), an abnormal first name and a normal surname (Lightning McQueen, Bruiser Bukowski, etc.), a normal first name (Chuck Armstrong, Hank Murphy, etc.), or only having one name (Fillmore, Sarge, Luigi, Guido, etc.)
Types of vehicles
Ground vehicles are the most abundant type of vehicle in this world. At least three types of vehicle exist: automobiles, trucks, and buses. Bikes, motorcycles, ATVs and segways do not exist in this world.
Aircraft/spacecraft, trains, and boats/ships are typically used as transportation for the cars due to their larger size. Aircraft come in at least four types: planes, helicopters, airships, and spaceships. On some aircraft, they appear to either sport goggles or helmets on their cockpits. Trains are mostly diesel or electric, with some occasional steam locomotives. On steam locomotives, their eyes are located on their front windows behind their boilers rather than on their smokeboxes like the characters in Thomas the Tank Engine. Boats/ships are the largest of these vehicles, and are often either large ships or speedboats. On some ships, their bridges resemble a ship captain's hat.
Animals are also carified, either appearing as tractors (cows and deer), combines (bulls), bulldozers (also bulls), miniature cars (insects and rodents), planes (birds), or trains (snakes), snowmobiles (also deer), or giant dump trucks (unknown). Other than these, no other animals exist in this world. Some logos appear to have uncarified animals (such as the Dinoco logo) despite this.
