Here are several that just came up.

When I picked up my new trailer at the RV dealership I was handed a stack of business cards and pamphlets. Wait....... am I to understand then they want me to do the salesmen's jobs for them? For free? Yeah, I was peeved.

And in the vein of trailers - this always seems to happen - I hate that other drivers fail to give leeway or show any sort of acknowledgement and courtesy. I signal well in advance of my lane change and they vroom up closing the space instead of allowing me adequate room to safely move into the lane. This is especially bad in merging traffic where I am rapidly approaching the end of my lane.
