It occurred to me one night last week, as a tailgater was trying to convince me to drive at 65 miles per hour down a narrow country road in the dark, that we need to breed bioluminescent deer, bear and moose.
Speeders at night apparently only expect to have to deal with lighted obstacles. This is clear from their foolish insistence on driving at speeds that would be idiotic in daylight, let alone at night. They obviously can't imagine a furry flank suddenly appearing before them in the murk. And, even though we're in the middle of winter, they can't possibly encounter a patch of ice. All they need to worry about are other cars.
Sad-- but too infrequent-- experience proves otherwise. But bioluminescent animals would solve that problem.
Later we can work on chemical additives in road salt so that black ice would glow, too. Perhaps it could even spell out the word "ice," in menacing, wavery letters.
