Mostly they rock from the waist up .

I too have seen many, many do this over the years, they stop when ambulating but begin anew the moment they stop .

In the 1970's there was a guy who come as regular as clockwork, stop across the street and back up against the wall and begin a swimming motion with his arms as his head scanned the passing traffic left and right .

He'd go on for a while (I no longer remember how long) then abruptly stop and walk away normally .
