A few days ago as I drove home for my lunch break I noticed that there were a few places where wires or small cables of some sort had been taped to the road. The wires ran from the street all the way to a small box located in the median.
Why were there two sets of wires and small boxes on my commute? Dozens of cars would run over them in the course of a day. What if I were the 299th car to run over the wires and the boxes were rigged to explode at the 299th car?!
Someone told me that the wires and boxes are supposed to count the number of cars that drive down the road for upkeep purposes. But how easy would it be for someone to rig the little boxes?
