You are right, they do seem to be in increments of 10 which makes it even worseI am seeing 10 mph increments on the speedometer, if I am not mistaken. It would make more sense to me if it was in 5mph increments, but it isn't. ... Heck. Put it in 5mph increments and change the color to anything but white and I might like this dash. Unfortunately, white will be nigh unto impossible to read in the bright summer sun.
