This device is real and the manufacturer shares some videos online
that make clear it’s possible to control these things pretty well. Is that Washington Square Park? I like that none of the pedestrians even break stride for this guy. The device fits into its environment pretty well.
Available online from various sources for about $170.
He makes it look kinda fun. I could think of worse things to do when hanging out in the park.
