I find that quite often (and I am very cautious as a result) that motorists assume that I am *very much slower* than they are - so at a 4 way stop they try to take my turn.... even if I have arrived much earlier than them, they figure they can out accelerate me. I find this to be frustrating (and, to about 15mph, often untrue, unless the person is being a complete @sshat and flooring it) I also find that even though I generally take the middle of the lane at intersections, people still like to sneak up on one side or the other and go with me.... This tends to muddy the whole pond about who's turn it is. Especially right hand turners... even when you are in your car, around here people really like to try to make more than one lane at stop signs where there isn't... yes there is a clear spot, to 30 ft from the intersection it's a parking lane, but there's no parking after that for visibility.... no that doesn't mean it's a turning lane.
