Are you saying more reflective road surfaces aren't safer at night? You should let road departments all across the country know that. They have used several different methods to do that since the mid 20th century.
I have been all over northwest, NEVER see asphalt based roads being painted or made white in production. The Asphalt roads are always
BLACK.
Meanwhile some research are showing that it is a NEGATIVE benefit since the production of "white paint" is energy intensive and costly.

Not all cool pavements are created equal
EXCERPT:
"Cool pavements can help keep cities cool, right? Yes, but according to new research from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), many reflective pavements have some unexpected drawbacks relative to conventional pavements when considering the entire life cycle of the materials.
Scientists in Berkeley Lab's Heat Island Group, in collaboration with the UC Pavement Research Center (UCPRC), the University of Southern California (USC), and thinkstep Inc., conducted life cycle assessments of conventional and cool pavements. Looking at the technologies over a span of 50 years, including manufacture, installation, use, and disposal/recycling, they found that the extra
energy and emissions embodied in cool
pavement materials usually exceed the expected energy and emissions savings from reduced space conditioning (cooling and heating) in buildings."
