Why does Google Earth never show people even in busy street scenes?

Based on the apparent resolution of automobiles;

And considering that you're looking straight down on people standing or walking around...

Each person, even very fat people, would take up One Pixel or less,

Which means that they would just blend into the background, lawn or street.

Occasionally; You can in fact see people, Such at Austrailia's Bimbi Beach,

But these Aerial Images were not taken by Satellites.
