Crazy North Carolina Drivers

OK...here's something that drives me crazy about North Carolina drivers! They do not seem to know what an on-ramp is for on the highway.

The object of the on-ramp is to allow you to merge into the traffic flow on the highway. This means that you should look over your shoulder and adjust your speed accordingly as you merge on to the highway. It DOES NOT mean that you should stop at the end of the on-ramp and wait for an opening! What part of merge do we not understand?
