Are you referring to he whole thing, that the bird is not confined and will go flying if an accident happens???
The whole thing makes me crazy and yet so many people will use that sort of thing or just let the bird loose in a car and think it is just perfectly ok. I have to wonder how many people have lost their precious birds because of this one stupidity. Those would tend to be the people who don't admit to what happened to the love of their life, especially after being warned.
I still will give them a heads up on the dangers, and possible law suits that could be involved what with so many sue happy these days.
