Driver's Bluetooth Sender   (+1)  [vote for, against]
Gets your message across to other drivers

The Bluetooth Sender is a device for your car which will scan for available bluetooth handsfree devices in nearby cars, detect what direction they are, and offer you a menu of which one to send your message to. Once selected, it attempts to connect, trying common default PINs for access. If successful, you may then speak your message, which is transmitted to the chosen bluetooth device. The device listens for a response and plays it back to you.

If you are not satisfied that the person has heard you, you press the "try harder" button. In this case, your Bluetooth Sender will scan the FM frequencies for sound that matches what it's receiving from the other device, and if it finds a match, send a directional FM transmission of your message, increasing the signal strength until it successfully hears the signal back over the bluetooth link.

Once you have finished, your Bluetooth Sender disconnects.

Please check your local laws before use, and only use in a safe manner.

Likely to get their attention. [8th of 7, Jun 15 2015]

// scan for available bluetooth handsfree devices in nearby cars, detect what direction //

That's a tricky problem, given that the power output of such devices is low, it's inside a metal vehicle, and it's very unlikely to be in pairing mode.

Not practical in the BT 2.0 & 3.0 specs.

I'd just give them the finger. Works like a charm. Quick too.

That's good, coming from a man who keeps a rack of loaded blunderbusses by the front door, each with a neat little brass label inscribed "Carol Singers", "Vicars", "Tramps", "Charity collectors" and the like, and all with notches on the stocks.

Yes, we have read the sign that says you're just keepin' up an old family tradition started by the 6th Earl, dontchernow, but the corona of dried blood, withered flesh, and bone fragments mixed with pulverised party political leaflets, suggests the tradition is honoured both in the observance and the breech ... the breech in question being the double-barreled 4-bore with "welsh" inscribed on its little tag.

And another thing - it's considered unsporting to have your target restrained by four burly gamekeepers while you take aim through a haze of alcohol fumes. Even your Great-Uncle Reinhardt (who never goes out in daylight because Mossad and the Wiesenthal Foundation are still looking for him) was hear to tut-tut when you took out those little twin girls who came trick-or-treating ... although it's more than likely he was just bewailing the waste of experimental subjects.
