A post-apocalyptic Thundarr world would be the same without vehicles. What made Thundarr so fun was the notion that our vehicles did not decay 3000 years later. If some mutants patrolled a territory on motorcycles, we could recognize them. If Ariel needed a helicopter to work, she would animate it with magic. Water faring vessels looked like great wooden barges with functioning battleship cannons patched on them. That cartoon was based in the 1980s - it's 2019 now. Look how much technology has leaped ahead! We got hand-held phones with the computing power unheard of back then. He have personal aircraft units, solar-powered vehicles, and battery- human horsepower hybrid cars. [yo utube:https://youtu.be/bFFeAU7v_QI] We have smart homes, 3D printing, wireless electricity! The Thundarr realm is set just over 100 years after the world ends. So it is plausible that cars and other vehicles are not complete piles of rust. If we stayed true to the 3000 years post-apocalypse timeline, cars would be gone. The just don't make 'em last forever. Go watch some Life After People videos if you don't believe me. So how is the world different? First, we have limited access to incredible technology. Tech that engineered interstellar space travel has fallen to earth. Beings that know about star travel and the technology associated with it can rig the junk on our planet with some high powered stuff. So not everything needs wheels. Some vehicles may have hovering power. Some may have a blaster cannon latched to it. Other may have high tech sci fi computer systems in a rust bucket. Wizards can use telekinesis and perhaps supply a power source to an otherwise inanimate vehicle. Some Wizards can transform a vehicle into a monster. Oh yeah baby, Thundarr had elements of The Transformers before it was popular. Imagine a villainous Wizard in your way, then with a gesture, the junkyard of cars around you begin to move...
