It is amazing that in spite of being big, red, covered with flashing lights, people seem surprised when the fire truck roars up behind them. Being conspicuous in every way is apparently not enough for a fire truck to take attention away from texting while driving. It is neat to see the semi-conscious driver jump when the air horn blasts, though.
