As a pedestrian riding your bike in New Jersey, you have every right to use the roadways the same as any other person in a vehicle as long as you obey the traffic laws. You are legally allowed to be on the roads, and other drivers need to be aware that you're going to be there. They shouldn't be trying to pass too closely to you, and you shouldn't have to worry about getting hit by someone who isn't paying attention.
Sadly, there are many pedalcyclists who are killed each year in motor vehicle crashes. Their deaths account for around 2 percent of all the fatalities that take place on the roads, showing that their numbers aren't insignificant.
