For the longest time, I would use Maps and see myself driving, but the map never rotated in relation to the direction I was going. This bugged me because it seemed like a simple GPS feature that Google should have included. Well, with the newest Maps update (ver. 4.4.0), you can now go into Navigation and let it run without a destination and still see your location on the map and it'll rotate accordingly. Click on the Navigation icon from the app drawer. You'll see a list of options and at the top where it says "Choose Destination", you'll see a little map icon on the far right. Click that and now you'll just see a map showing your current location and it will follow you when you drive around. Edit: Removed navigation screenshot.
