What does it mean when Google Maps says "moving"? I left work like it says , drove to my friends which you can see , but it says I was moving from 8.23 am -2.30 am but that I didn't leave. I don't think I accidentally turned it off when I left that morning. So what does it mean to say moving.

From the last point (Harding's) to your current point, it assumes that you were moving, probably because of changes in distance or because of movement.
