--- Post updated --- These papercraft vehicles are great for practicing Blender usage, not sure about origin of this one, but search engine found it from Pinterest Besides I don't have ink for printer, so it is about same to craft them in Blender and put to maps at random locations. It takes roughly 1 hour to make one with lack of skills. Just make rough outline of it in 2D plane, transparent material, then knife out parts not needed, triangulate and quadify, bend sections to shape placing 3D cursor to hinge point and use 3D cursor pivot. Extruding, welding of vertices, UV mapping, one needs to train all those things that are useful when making real models.
Here is a weird crash on a light post. It's an old screenshot. The car kind of flew... and into the light post, wrapping around it. It stayed up there too, it was stuck.
