Sci-Fi series were the worst!
Do you recall the TV version of "Logan's Run" ?? It used a boxy "hovercraft" that would bump it's way across fields on it's not-always-hidden wheels.
Also, the last season of the original "Battlestar Galactica" (when they rediscovered Earth) used a pair of dressed-up "flying" motorcycles. Poorly done green-screen matte effects, no extra charge!
Another bad one was the "Landmaster" all-terrain vehicle from the movie "Damnation Alley". Weighing in at 10 tons, it's 391ci Ford V8 had a tough time getting it moving.
The only good Sci-Fi series car was the Dodge Charger from the Blade movie with Wesley Snipes.
