Anecdotally, I see them all the time in my neighborhood, and they seem much more attentive to pedestrians and stop signs than regular drivers. Drivers in this neighborhood act like they own the place even though there’s probably an equal number of pedestrians out at any given time.
I’ve also seen one of them fail to pull over when an emergency vehicle was behind it, so I buy that they are causing some problems.
Thanks! I took the nib and feed out, cleaned it thoroughly, and reseated it, and it seems to be working well now.
