I think there is something to be said about making oneself more visible, extra lighting at night especially. I am a fairly attentive driver but the number of times i've had a fire engine or ambulance sneak up behind me makes me leary of EVER assuming someone saw you, heard you or even knows you exist.
the only way to keep yourself safe on a motorcycle is not only assume that you are completely invisible to literally EVERYONE but that most of the drivers out there are intentionally trying to trick you into running into them by changing lanes unexpectedly slowing down, not signalling, speeding up, swerving, drifting lanes, and basically trying to run you off the road. watch everyone like they are your worst enemy and this is the one chance they have been looking for their whole life to grind you under their bumper and be able to claim "I just didn't see them there"
stay safe people.
