This is pretty detached from reality. Many places in the countryside don't even have road lines, never mind reflective ones. People walk out in the countryside all the time. Animals are a very big reason to have bright lights in the countryside, too.
Headlights dazzle animals, which is why they stand there staring into your lights until they get hit. The less light your car is giving off, the more chance wildlife has to get out of its way becasue it can actually see your car not just a massive bright light like the sun coming towards them.
