Many of the drivers are afraid to turn onto NSI and use the right lane when open, then merge into the straight-ahead lane; they stop traffic from the ramp. The same problem exists on the exit ramp from 386W onto NSI north. Drivers will pass the stopped ones on the shoulder, often in frustration, to either turn right onto Forest Retreat or merge into the straight lane. This is somewhat hazardous and illegal, though they do create the additional turn lane requested by the writer.
