I don't like having anyone near me when I drive. I will seriously adjust my speed no matter the speed limit to make sure there is at least a good 15 feet between me and any car. This makes driving in rush hour or lunch time traffic unbearable.
When I've just met someone and they're talking to me like I have known them for years. This seems to happen at work a lot when I'll be working with someone new and then they'll go off for a while about all facets of their life, talk about their friends like I'm expected to know who they're talking about, etc.
Pretty much other things that have been listed, except for the birthday thing that Czech has a problem with.
Oh wait, another one is being asked to explain things and then being cut-off with a question about the thing I was getting ready to explain. This happens at home a lot... in fact since I was three, so it's one of the reasons why I don't really say much when people ask my opinion about something.
