No-Go Kart is based on the oboroguruma ("hazy carriage"), a youkai embodied as a ghostly oxcart with a huge face where the coachman's seat would be. This youkai roams around dark streets at night, instilling fear with the sinister creaking of its wheels.
Oboroguruma were originally a fixture of youkai picture scrolls with no real backstory, but Toriyama Sekien theorized the creature incarnated the resentment born from people fighting over parking space for their carriage during the overcrowded festival seasons. In modern times, oboroguruma tend to be portrayed as modern wheeled vehicles instead of oxcarts.
"Mayoiguruma" means stray carriage.
"No-Go Kart" is a play on "no-go" and "go-kart"
"Indiligencio" is a corruption of "diligencia" (stagecoach).
