Improving Blender 2.82 EEVEE Rendering Precision for Large Scenes with Small Objects

The sole purpose of this article is to document my beginners' findings. The problem and the solution are trivial. But I will be happy if it helps anyone else :) I'm working on a small animation project. Recently I wanted to make some test animations with a truck driving on a road. The road was modelled with a Bezier curve with a simple thin flat road profile. Since the world is fairly simple I wanted to render it with EEVEE. However, the first renders revealed some unpleasant glitches, i.e. the road became transparent in some frames. The same render with CYCLES had no artifacts of this kind. This appeared to be a trivial problem. However, googling according to my understanding of the problem gave me no answer. Initially, when I started modelling this scene, I set the Clip Start of the camera to 0.01 m. This way I could work with the scene objects from very close distances. This in turn has a very dramatic effect on rendering of small/thin objects far away from the camera. It just can

Initially, when I started modelling this scene, I set the Clip Start of the camera to 0.01 m. This way I could work with the scene objects from very close distances. This in turn has a very dramatic effect on rendering of small/thin objects far away from the camera. It just cannot be rendered precisely. As soon as I set the Clip Start to 1 m all the artifacts disappear.

If I google for Camera Clipping, then I get the right explanations. However, when I google for "Blender EEVEE render precision", "render small objects on large scene EEVEE precision", I didn't get any useful results.
