Well, it finally happened to me. I haven't heard these words from a motorist for a long time, not even on major thoroughfares.
Friday afternoon, I was doing my usual commute home. On Belinder, in Prairie Village, KS, a quiet residential "feeder" road, a pickup passed me. The passenger said,"Get off the road!" as they drove by. Strangely, this is one of those two lane roads that has ample room for cars to park on both sides without hindering thru traffic. So, it isn't as if I was in any way impeding this (ad hominem remark deleted).
Usually, motorists are friendly and nice to me on my commute, so this was strange for the roads I take.
