The police and road workers do their job while standing on the side of busy roads. Moving targets are harder to hit. Never is there a guarantee of "not getting hit" but likely better to be moving with traffic as it helps to reduce approach speed of on-coming traffic. This is why I always tell people to never ride on the wrong side of the road. Doing so reduces driver reaction time ( which is never a good thing ).
What is NOT BEING SAID here is; How many people get killed ( or injured ) because they had no "see me" lighting? There is no way to answer that because there is no way to gather the stats if the question is not asked at every accident ( and then posted publicly ). There are always going to be accidents. If you can remove ( or lessen ) one of the probable causes; ( Not being seen, being poorly seen or seen too late ) you are one step ahead of the game.
