at dusk and when the roads are dark (or so it seems), I don't know how they came up with silver cars other than the numbers, which can very well be coincidental. I would think if their results were derived from an estimated correlation due to lighter colored cars being more visible by other drivers, that all light color cars would succeed in the same way. Their last line...." They did not explain why car color has an influence but said previous research suggested that white or light-colored cars are less likely to be involved in a crash than cars of other colors." seems to be more correct.
