You know, whenever I go to Columbia for a hospital visit or otherwise I have to go through at least one of those silly round-abouts. These all way stop sign replacements would be all find and dandy if they were standardized, but each one seems different. You have to be an expert cartographer to understand and interpret the sign before you get to this crash-site creator. Merge in the left lane if you want to go north, stay in the right lane if you want to go south or east, and merge to the third lane(?) if you want to keep going around and around the round-about. The last time I approached one of these round-abouts I was started facing one direction with the intent to finish facing a completely different direction, but ended up facing the same direction that I started. It appeared that it didn’t change my trajectory at all.
