The last one is informative. There was a collective of corporations that made planned obsolesce the major form of business. Profit maximization at its best. Capitalism is not sustainable as it does not allow the making of things to their lasting as long as possible.

Is it a coincidence?
Yes
If it were actually true, which it is not.
The Apex of the great Pyramid of Giza is on the line of latitude 29.9791750 N, Not 29.9792458 N meaning the speed of light equivelent is somewhere around the bottom left hand corner of the pyramid.
Any latitude between 29.980150 and 29.978150 passes through the structure

Originally, the pyramids were covered in a white casing stone which gave them a smooth appearance. I think as a shape they occupy two states at the same time, that is, when external pressure is exerted the structure withstands it well and when internal pressure is exerted the structure easily weakens. As always they remain fascinating, especially, when you consider the engineering feat to move the huge blocks of stone.

The electric car conspiracy stuff is easily explained. Some of the earliest cars, throughout the world were electric. Some were even steam driven. Cost and convenience, at the time, made gasoline and diesel the choice of users.

Erosion and other factors haven't changed the pyramids coordinates at all over the years? That is interesting

Not such an eerie coincidence when you realize that how time and distance are measured is subjective, if not artificial.
