OMG, Imagine someone cuts all the brake lines in our current cars, or hacks the traffic system and makes all the lights green at the same time, or puts nails on the road, or turns into the boogie man and "gets" people. Fear mongering is not the way to view problems, or to make our society better. We need to improve things, not live in fear of what "Bad" people could do to us.
