Idea for an invention:
Some kind of remote access PA system that would allow you to speak to other drivers on the road via their stereo system. Imagine being able to *actually* cuss out that a-hole who cut you off, instead of them just ignoring your honking, mouthing of obscenities, and rude gestures. Or even better: for those crazy, ultra-right wing tin foil hat conservatives that have ‘THE END IS NEAR’ bumper stickers – how awesome would it be to speak to them and pretend to be the voice of God? SO AWESOME.
