avg speed wrong?
i drive an 08 is 250 and on the display console my average speed seems to be wrong.. is it just me or others have the same problem? i am going about 60 to 70 and it shows me moving in about 50s.

ChickenAss, this is the overall average speed of your entire trip, not just what you are doing at the particular moment.

Yup, people need to think about weighted averages. If you leave your car at a stop for 1 minute, then zoom up to 60 MPH (ignoring the 15 seconds or so it takes to get up to speed), then go for another minute, you are only averaging 30MPH. You go for another minute, and you're up to 40, even though you felt like you got a good stretch of 60 MPH in there...
You can verify your avg speed simply by tracking how many miles your trip was and divide that by the time it took, from the time the engine is on to the second before you turn your engine off.

Our speedometers are off a little (I think they read faster than we're really going). I wonder if it would be an accurate way to gauge just how off they are, would be to set the cruise control to, say, 60 mph, and then reset the avg speed while driving, and see if the number changes any after about 3 or 4 minutes. The longer you drove, the more accurate the avg speed reading (theoretically, anyway). Then, would the percentage error apply to all speeds, or not?

I'm not sure also though, because sometimes or some days when I do drive 60mph I seem to be going slower then what it was before.
