Lights after dark?
Just be vigilant around side streets and driveways.
I'll ride on most roads, including arterials (near right, and sometimes left curb), and cars can usually figure out how to pass.
However, there is one grocery store exit where I have to make a left turn and for some reason traffic is always a mess. There is a sidewalk where I don't think I've ever seen a single pedestrian, and if I ride "salmon" on the sidewalk a couple of driveways down, I can usually get across pretty easily.
Anyway... I usually avoid sidewalks, but it can be situational. I do like MUPS.
