Hate Mail For The Blind

Why would the National Federation of the Blind be getting hate mail from environmentalists? One of them even said they hoped the blind would be the first to drown after the seas rise from global warming. You have to be a special brand of mean spirited to send hate mail to the blind. This seems nutty but it's true. The blind have a beef with hybrid cars. They're down with the whole green movement; they would just like to be able to hear a car coming at them. It turns out that at lower speeds even the super sensitive hearing of the blind can't hear them drive by. For people used to relying on their sense of hearing to protect them, the prospect of silent multi-ton vehicles gliding down the road would be pretty freaky. I wonder if this problem could be solved by attaching deer whistlers to the front of hybrids.
