Just thought of another one my gripes.
Knights of the bloody road, you get them in every town who think it's okay to just stop in the middle of the road, just to give way to some gimp, when they can wait normally for a gap in the traffic...
People who butt in to conversations, instead of waiting for a pause or gap.
It's really infuriating, especially when one example is soon to be a relative :facepalm:
