  1. I'd suggest it could be more dangerous for the emergency workers. I had to pass a couple of cop cars working some kind of accident and even crawling, it was quite hard to see the people working in the road with red and blue lights burning my retinas from 6ft away.

  2. I'm sure someone else has already commented but it's worth saying that these reflectors do not eliminate inverse-square law on either of the legs of the journey.

  3. Some places put reflectors in the road marking paint. Sadly, that's not the case here and the markings disappear when it rains at night. (Edit: Ah, you got to that). A lot cheaper than cats-eyes, I believe so can be used in more places.
