I'm not saying that getting run over is the cyclist's fault.
Nonetheless, there are methods that a cyclist can use to improve visibility, and thus hopefully decrease the odds of being hit, including high vis clothing, and blinking lights.
My current battery powered rear light lasts several days, and is bright at night. Not the brightest for daylight visibility though. I'm not sure it would last for 10 days, but it could be recharged during the day.
