I realize the humor in these posts about detecting illegal aliens, but you guys may not be too far off the mark.
I researched why 6 feet was used as the separation for social distancing during the covid hoax and stumbled upon the human toroidal field.
I don't think the demons wanted our hearts to interact with each other. Love, compassion, happiness, positivity make our toroidal fields extended far and wide, but fear, hate, sadness and negativity reduces the field to 3 feet. While our subconscious was in a constant state of fear i.e. masks, arrows on the floor, social distancing, plexiglass barriers, ect, ect, our toroidal fields extended about 3 feet, making 6 feet the perfect distance. I believe the toroidal field is the reason we can sometimes "since" someone around us.
I don't know if the reptilian demons have the same rhythmic energy emanating from their hearts, but if it is different, maybe flying cars can have sensors that detect the difference.

I think that absolutely may be true, Bijowi, and I will add to your analysis - albeit a more simple explanation.

Wartime President Trump repeatedly asserted during COVID for People to maintain "social distancing"...WHY?

The biggest threat to the American Public during COVID was not only MK ULTRA Mind-Controlled Assassins who are involved in all Mass Shootings, but MS13, Barrio18 and other Satanic Gangs and groups of Terrorists who were heavily armed (likely with MIL Grade Automatic Weapons) and brought to America for the specific purposes of ATTACKING THE AMERICAN PEOPLE upon the order of the Deep State Democrats, and they had not been all apprehended yet, so the Threat of Mass Shooting by even MS13 Terrorists was REAL, and targets (Humans) that are bunched up in checkout lines at a supermarket, for example, are very soft targets.

When Humans are spaced out 6', that would reduce casualties by making targeting harder and buy time for a CCW to engage the Terrorist.

IMO the distancing was a way to reduce herd immunity and thus further weaken the immune system. Same thing with masks and oversanitizing. 😇
