On my way to work, I have a left turn that bothers me. As I'm coming downhill there's a light, I turn left at the light and there are usually lots of cars piled up. Generally keep to the right and pass the stopped cars then signal a left turn when I get a chance. All in all, not that bad.
On the way home, I cross a major road. Just after the light before the road, a left turn lane starts about 1/4 mile before the crossing with the major roadway. I generally stay in the turn lane (taking the lane) for the first 300 yards to allow traffic to pass, but about 100 yards before the light I make my signal and move left when traffic allows or when there's no possible way anyone behind me can make the green, but drivers seem to ride up my arse anyway. Whether they don't see my signal, or it doesn't register, or they are just in a hurry to get to the light to wait for the next 2 minutes, I'm not sure, but it's the point at which I feel most exposed. Add the occasional 7-11 patron entering or exiting the parking lot on the right and the situation is enough to make me very nervous every time I ride thru there.
