So you're on the phone on your way from work talking to you lovely wife about how "interesting" her day was: she put the kids on the school bus, cleaned the house, cooked dinner, etc. As it should be. However, you spot a hazard on the road then have to quickly tell her to shut up lest her breadwinner end up in an accident. Thanks to a patent filed quite some time ago, all you'd have to do is push a button. This sends a signal to tell her to please pipe down ("shut up") so you can concentrate on not crashing. Hey, that's how the filing reads.
