Several police departments use them. I know San Antonio does also. I think if Honda were to market a police version of the wing, they would sell like hot cakes. Id take it over the Electra Glide any day.
I was talking with a friend of mine today who works for JSO (Jacksonville Sheriff's Office) and he said they have six wings they are testing to decide if they're going to switch from Harleys to Goldwings. It'll be interesting to see what happens.
