An early trial version of a moving pavement; the Travolator; is demonstrated in New York in 1924. It was supposed to help relieve congested streets.
United States of America (USA).
The wooden pavement has 4 different lanes: the first is stationary; the 2nd moves slowly; the 3rd at medium speed; and the 4th is the fast lane which has a row of benches.
A line of men in business suits and hats step up onto the stationary platform; then walk across the various-speeded lanes (like changing lanes on the motorway) and take seats on the benches.
Shot from above shows the men nonchalantly sitting on the benches; whizzing round a curve. Looks like a bizarre adult merry-go-round.
