I agree, Gbj. In some ways and at some times, slow drivers are even more of a hazard. Bad drivers are a fact of life. All good reasons to drive defensively.

Should confess that in my early 60's I am increasingly plagued by night blindness. Not a big problem on freeways because there are not approaching headlights directly in my line of vision. I fortunately changed jobs several months ago that mean I no longer have to drive 40 miles of 2 lane country road, infested by crossing deer on dry nights, and on which I was literally rendered blind by approaching headlights on rainy winter nights when it was dark by the time I left work at 6:00pm. Was wondering if I might have to resign simply from inability to safely drive come this next winter as I was well aware the night blindness was getting worse and worse. Although those were not heavily traveled 40 miles they were not lightly traveled either, and it was always a challenge to figure out, when traffic began to back up behind me, if and where I might be able to pull over to let cars pass. Has made me a bit more compassionate when I get behind an obviously elder driver who really can't safely drive the speed limit any more, even on dry rural roads in daylight. Easy to say they shouldn't drive. But also know that many in rural areas don't have alternatives to get around to the limited extent it is essential they do.
