Ok. I did it for fun anyway. I couldn't get up to 70 MPH average because of traffic. Instead, it's just a +12 MPH Average comparison. Here are the results :

ROUTE : 10 West -> 710 South -> 105 West -> 405 South -> Exit Freeway => Roughly 27+ miles

SCANGUAGE "CURRENT" Readings :
Code:
                   SLOW     FAST 
MPG            :   61.2     45.8 
Gallons        :    0.4      0.6 
Water Temp Max :  200.0    204.0
Miles          :   27.5     27.7
RPM Max        : 2135.0   2572.0
Hours          :    0.6      0.4
MPH Max        :   58.0     74.0
MPH AVG        :   45.0     57.0
WEATHER(.com) :
Code:
Degrees F      : 77.00      76.00
Humidity (%)   : 27.00      59.00
Dew Point (F)  : 36.50      60.00
in. Pressure   : 30.09      30.01
The problem (in my mind) is the difference in the humidity. Otherwise, these two express a decent comparison.
