Here is one I frequently take; Harbor Drive in both directions. As I approach the merge I turn my head and establish eye contact then drif across if I am certain its safe. Otherwise I stop and wait for a gap in the traffic. This happens a lot more northbound than it does southbound. The cars exiting the interstate north approach a traffic signal, then a guard gate where they have to stop, so this slows them down some. Cars exiting the interstate to SB Harbor have a sharp turn that slows them somewhat.
