I'll add my observations and experience  to Matt's.  I take a lot of trips
around Washington/Oregon that are mixed freeway/secondary road traveling.
Most of the time I've plotted my route on Streets & Trips to figure the
time/distance.  I set the options in Street & Trips to slower than normal
travel, set in fuel, food and rest stops.  And still run about 20% or better
longer till I get there than the predictions in the software say.  Example:
Last week the computer told me I'd drive for almost exactly 5 hours to get
where I was going.  So I figured 6 hours.  And the 6 hours was almost dead
on.  The predictions are based on ideal conditions on the road, not the real
world, especially when passing through more populated areas where traffic
congestion throws the 'average speed' concept out the door.
And it still comes down to "It's the journey dummy."
