They're in Flushing Meadows-Corona Park, the site of the 1939 and 1964 World's Fair in New York City. The street that they were on is low traffic and runs runs parallel with the highway, with a bunch of pedestrian bridges to cross the highways. There are also a lot of trails in the park. There is no reason for them to be walking along the highway no matter where they want to go as every possible direction has a pedestrian friendly route.

(Bridge in the video is circled in blue)
The park was built over an old ash dump which is why the rest of the area is pretty industrial.

I can't believe they destroyed the city to build highways, stadiums, rail yards, and parks!

It's a troll post playing up the urbanist trend to try and boost their new travel Instagram account.
Considering they got 264k likes, the trick worked.
