Common sense never dictates. Certain people drive at speeds that are ridiculous and then they claim the "slippery road" caused them to end up with the vehicle on it's roof. Somehow those four driving wheels didn't help them all that much, despite the claims of their friends and the vehicle manufacturer.

Once day, when they kill somebody, they might get some common sense for the remainder of their lives and realize that their excessive speed got them to their destinations a good two minutes faster than the traffic that actually had the common sense in the first place.

The average person is a moron.
