I bike roads like this, (and far worse) all the time. It doesn't look bad, because the auto drivers have plenty of open space to see you. I know you think you need a shoulder to ride on, but the safest place for you is about a foot or two TO THE LEFT of the white line -- in other words, completely and unmistakably on the road. This is safest because: A) Drivers are going to see you more easily and will slow down to get around you and B) you will miss all the broken glass, potholes, and other debris in the shoulder. Recently my partner and I were cycling in Ireland where the roads were much much narrower, and he pointed out that one ride in particular along a narrow and very busy stretch was complete confirmation of the safety of taking your spot on the road. When he tried to ride on the teeny itty bitty road edge, car drivers zoomed on past; when he held his spot fully on the road surface, they slowed down and carefully passed. It works the same way here. Perhaps you should try this on a weekend, when you know traffic is light? I see you are in NJ; I'm in equally congested eastern Pa. Read up on proper road positioning, take your time and gain confidence. Riding is a BLAST!!
