I drive around a hundred miles a day. The one thing that still gets me is people that insist on sitting in my blind spot on multi lane roads, the ones that will get off your rear quarter panel and just drive alongside at the same speed. I'm pretty good on situational awareness and knowing where vehicles are around me, but I've been forcing myself to look on every lane change, just in case someone snuck in there.
Other than that, I am a pretty easy going driver. I don't try to force things, even when I am more than capable of doing so.
