As someone who had three vehicular misadventures in eight weeks, I know how the 22-mph driver feels. However, it's possible he could have been cited for obstructing traffic, if the police had observed it.
I have just started driving without my throat being clenched up all the time, but my mouth is still quite dry at times and for the first few weeks, everything was going too fast and coming too close to the car. I forced myself to go the speed limit, and pulled off two or three times when I saw cars behind me. On winding roads, however, there isn't always a safe place to pull over. You wouldn't want to come around a blind corner and see a car, pulled over but not off the road, because there's no real shoulder there..
The road to my job is crooked as a snake's back, and it's snowing again tomorrow. (Big sigh)
