Strangeness.

According to Google Earth, my odo (and speed I assume also) is under-reporting by about 5.7%. Definitely not the 19.8% I was expecting.

I'm not sure what that means.

Either I calculated the differential difference wrong, or maybe I've been working with wrong numbers all along.

Anyway, I still really like the way it drives now. The car feels much more laid back.
