This little horseshoe is part of my commute every day. It's the quickest way onto 787 from my part of Madison- if people COULD DRIVE. Unfortunately, you get assholes that don't know how to drive, and a yield sign that doesn't belong there.
Folks, the people coming around the horseshoe have one lane. The people merging on get a COMPLETELY DIFFERENT LANE. You don't need a full three car-lengths before you attempt to get on, the tiniest gap between cars is good enough.
