Most helicopter require only two rotors. That “flying car” is a oversized manned drone. I think most of these dreams of flying cars flys in the face of aerial hazards that jets sometimes encounter like birds and meteorological phenomena like downdrafts, etc. Too many ways that it can crash. It doesn’t take much altitude to have a fatal crash, too.
On one of Andrew Zimmern’s tv shows, there was a segment where he showed a chef in Richmond VA who killed pigeons by flinging rocks at them and fixing them for dinner. I forget the restaurant he served them but “Squab and Squirrel” would’ve been a catchy name!
My wife has seen all manner of filth and destruction in bathrooms by “customers” when she was a manager/ franchisee owner of two convenience stores. We’re talking about excrement all over the place. Some people can be more disgusting than any animal.
Denier, denier, pants on fire. ;-p
