I embarassed myself a little a few weekends ago when I caught myself using my turn signals up in the woods on logging roads. Nobody else anywhere around. Oh well, it's a good habit.
But I can't bring myself to trust others' turn signals. I see them, but I'm not willing to pull out in front of them until they actually start turning. Maybe I've left my own signal on a few times too many.
I ran a stop light in Salem (in my car) once, and was only spared because an on-coming driver was actually paying attention and let me by.
