Avoidance - Don't do what I did once, which was ride along with a non-instrument rated pilot at night or in anything but good weather. Night VFR is possible, but we ran into light rain coming back from Plattsburgh and only got back because we were lucky. Luck isn't a good plan.
Pilots have their minimums, both the required ones and their personal ones. As a passenger, I have my own, too: I won't fly commuter sized airplanes in the winter from airports where it snows. I won't fly in single engine aircraft at night. I won't fly with a non-instrument rated pilot in anything but daytime and good weather.
Flying in a light plane, I watch the pilot do the pre-flight, and when I'm in the air I'm scanning for traffic much of the time.
Maybe a bit paranoid, but I don't have to travel much for work, so I can get away with it.
