Detecting so called "silent SMS"

I have been tempted to use this method to prevent Wayz, etc. from sending impatient commuters through my neighborhood. I live on a street that is not a good through street, has limited visibility because of a hill, and increasing numbers of children at play, yet yahoos still come barreling through at 45 mph, driving with their knees, texting as they come. I’m kind of surprised there isn’t a product to spoof traffic jams yet – I’d buy one.

More directly related, I was in the mountains recently and wondered why the scenic road I was on was showing up as totally jammed on the nav system, while actual traffic was rather light. I then realized it was counting all the cars pulled over at the scenic overlooks as cars stuck in traffic, and had to laugh.

Sorry, I know this is a COMPLETELY inappropriate aside for this thread. I promise to say no more.
