No it's not just you. I flash drivers coming the other way and wave at them and see if they wave back. (Merc and BMW drivers NEVER wave back! Mini & Beetle drivers are the most friendly.)
I like driving at 30 dead on in the town and taking corners, junctions and roundabouts at 30 as well. People get annoyed you are "going slow" then they can't keep up in the bends. Obviously I only do this where it is safe.
