Sounds like some of the vehicles of Eternia. Fast-moving. Exposed to elements.

[Some capable of flight, like the sky sled.]

They are not at risk from larger vehicles though, as there are not enough of them to pose much threat.

[Eternia has technology. Advanced technology. It's not a technological world, and people are as content to get about on foot or use what might be dubbed "archaic" modes of transportation to get about as they are to use advanced tech vehicles.]
