I buy insurance for lots of things. It is unlikely my house will burn down or my car be in an accident. But I pay over a thousand a year to protect those items, just in case. I believe that it is difficult to see the margins of the paths in the dark, especially in the rain or when an oncoming car or cart causes my pupils to constrict thus reducing my night vision. There is no question that having a bright marker on the margins of the path will enhance my ability to determine the curves of the path. Will it actually reduce accidents? No data because only a place like TV could produce such data. Is it worth $7 a year for a margin of safety, I think so. Anyone who claims that visibility is good on the paths is simply not being honest. This is 2 cents a day per household.
