The distances you mention for viewing are obviously for people with very poor eyesight, the distances for good eysight are probably 3 times as much. If anyone needs to be that close to see the difference then they will fail the sight test for driving. I am a pensioner and I can see the difference between SD (standard definition) & HD at far greater distances.
