Why hasn't Dogging caught on in the States?

The only incident I remember that cums close is a few years ago in a Restaurant parking lot. A Husband and Wife sat down in the booth next to me and my friends. He went to the restroom and Wifey joined us and was quite flirtatious. We thought it was a big joke. My buddies and I were just having a few beers watching sports. They tell us to meet them outside in the parking lot as they leave a few minutes later.
We hightail it outside and proceed to get our dicks sucked in between some cars. Hubby was jacking stuff while watching his hot wife suck 3 dicks.
Is this Dogging?
