Tom Vanderbilt in Slate Magazine writes about The quest to design a better stop sign.
[T]rying to improve driver behavior through better signage is as futile as fighting illiteracy with better fonts.

Not all safety improvements are futile, but there is a response, so drivers who are protected use some of the safety improvement to behave in a riskier way, as in the video below. This does not imply they necessarily die.
The NY Times says: Traffic Paint Shortage Threatens Roadwork
The scarcity stems in large part from the shortage of an obscure chemical compound called methyl methacrylate, one of the key ingredients in roadworthy paint, which must be sturdy, long-lasting and reflective.
