Just think how much better this world would be if the entire community stopped to think each time it suffered a traffic fatality. It might get people to drive more carefully and sparingly. It might get more people to wear seat belts. It might get more drunk drivers off the road. If the community would stop and think, each time there was a traffic death, it could get more people to use public transit.
Public transit has a much better safety record than the private automobile.
Remembering traffic fatalities might get people to live closer to their jobs and do more walking or bicycling. The entire oil economy needs to slow down a bit for safety. If safer pipelines add to the cost of the product it could be a blessing in disguise. There is a very active listserv about the Whatcom Creek disaster and pipeline safety issues.
