I watched this video last night and
found it fascinating

The idea was to make each car in the US
a combo wifi repeater..... so that each
car sends and receives data but also
relays other's data as well.

This would create one huge shore to
shore free wifi network such that the
economic implications would be enormous.

How feasible is all this?

And can one easily create a mesh network
in their home or even neighborhood?

see the video

A similar networking is already in use in police radios.
In this system, each cruiser carries it's own "repeater".
When grouped together at a scene where multiple cruisers are present,
only one is assigned as the "master" and all officers transmit through
it.

Networking a million cars wouldn't be all that difficult. With
computers the size of small flashlights, one could easily install a
unit in any car they want.

Let's say you had 4,000 networked cars lined up between NYC and LA.
How long would it take to contact the end cars?

Then why even put the transmitting units in cars at all?
You could have them mounted on street poles as needed.
