Careful observation confirms that you are correct on that second question. I spend way too much time on I-75, and the only cars driving at the speed limit are in the right lane or on the sholder where they have to go sometimes to keep from being run over by trailer trucks. The middle and left lanes seem to be reserved for ten mph over and 20 mph over.

And I agree that passing a sign might be painful, especially if it is mounted on a steel post. But my point was that "slower" is comparative, and is meaningless unless you know what you are comparing it to. (I like to end sentences with prepositions. It's the rebel in me.)

I think I need to explain my concern about the "straight ahead signal." A short distance from my home I come to a four-way corner that is a two-way stop. Hwy 11 goes straight through, and when the traffic clears, I have to deal with the moron at the stop sign across the highway. His signal is usually not on, but I know from experience that he might go left, right, or straight. Sometimes he will wave violently at me to go ahead and make my turn so he can run into me and then tell the cop how I turned in front of him. I will usually go if I am turning right, but about half the time I need to turn left. In that case I pretend that I don't see him waving, so that sooner or later, he will go ahead with whatever he wants to do. If I am lucky, there won't be another moron behind him.

Did I mention that this pesky intersection is at the crest of a hill, so that it is difficult to see oncoming traffic?

I'm sure that drivers with "straight ahead" signals would never get around to turning them on, so it's a moot point.
