"They" do what all the time? Drive too fast in fog? Yes, because most get away with it too often. I am amazed at people's willingness to follow a mass of cars at 60 mph less than a car length apart.
I imagine the people in this particular wreck will not repeat that behavior, unless you think it is the same people involved in all these pileups everywhere! ;~D
REPEAT BEHAVIOR: These are the same people who will vote for Davis, again-- even after what he did to wreck CA's economy, as he raised $70 mil in contributions.
