Average speed for segment
A->B: 90km/h (55.9mph)
B->A: 18km/h (11.2mph)
This is a one way segment B->A . It's 46 meters long, and has 90 deg turns at both ends. I highly doubt anyone is doing 56 mph the wrong way on this short segment.
I have noted that the WME Color Highlight script seems to have a bug that puts the decimal point in the wrong place as well. You'll see 4000 mph when it should be 40.
However I am still finding segments that have skewed speeds.
