I've noticed a few things in 3.0 that I never saw before. One road had flashing yellow lines parallel to it on both sides with small yellow circles with the number 30 in it. This road is not under construction and the speed limit is 45. I see this at all times of the day including 5:30 am when there is no traffic. Also, on freeways I see a bunch of green dots. They don't seem to correspond to anything except maybe off ramp starting and ending points.
I was wondering if there is a pdf or file somewhere that has all the changes 3.0 delivered. I searched the forums and there wasn't anything that I could find.
