Ehh... The doesn't really affect service. The bus stops, and lets passengers on and off the same time it takes at other stops regardless of if there is a coming... however, the area between Ocean Avenue and Coney Island avenue on Avenue M has traffic at times.
That is very true. There are a lot of people that may not be mindful of what they are doing, like crossing the road on red.
One other thing that causes this problem is because when there is a 30 minute interval between busses, and then there are busses that are 10 minutes behind that bus, and can easily catch up due to the accumulating amount of riders waiting at each stop, and then all three stay clustered because one bus gets one stop, the other gets another, and etcetera. The thing is, I don't understand why the second bus is leaving the terminal 30 minutes after the first one.
