In addition you get better miles per gallon if you keep a steady speed. 
It always amuses me to watch muppets racing up to the next car and then 
stamping on their brakes. If they do it too clumsily the resulting 
shockwave propagates back down the traffic stream at a speed of roughly 
vehicle separation distance/reaction time. Phantom congestion occurs and 
propagates upstream of the original event with no discernable cause.

You can sometimes see the wave of break lights approaching on hilly 
terrain under high flux traffic conditions. Paradoxically at the busiest 
times decreasing the maximum speed limit and enforcing it speeds up 
traffic flow by reducing turbulence. UK smart motorways adopt this 
strategy (and also using the hard shoulder which I don't like).
