New device lets drivers communicate wirelessly between cars

Unintended consequences dept:

Japan is user-testing a new device that lets drivers send messages wirelessly to other cars. This doesn't appear to be the "geddout of my way you idiot!" kind of message though, but using GPS and in-car navigation systems to let you know a car or hazard is coming up nearby.

This apparently is thought to be a good idea in Japan because half of all cars there have GPS, compared to 10% in the USA & Europe.

I see this hasn't prevented the driving masses from suggesting their own, well, rude things they've apparently been waiting to say to other drivers!!
