I will let Hemi give the optical metrics required to resolve a "logo on the
side of a truck"

Well, if you get in top of a high bridge looking over a major highway, you will
not be able to see any logos on sides of trucks. Although, you will be able
to see any logos on top of the truck.

Same with licence plates. The licence plates must be looking up so you can
read them looking down.

As soon as someone says they can see licence plates from so many miles up I
laugh. Licence plates are designed to be read from the road and not from the
sky. Same with logos on the sides of trucks.
