For years Detroit Democrat John Dingell and the Detroit auto companies have been telling us that fuel-efficiency (achieved partly with smaller, lighter cars) is dangerous. The media dutifully reported this. Now researchers from the University of Michigan and the Lawrence Berkeley National Laboratory looked at the accident statistics and "found SUVs are just about the most dangerous cars on the road for all drivers." Planet Ark is an interesting on-line outlet which provides worldwide environmental news and pictures originated by Reuters -- with a slightly greenish tinge, an unusual find in a hard-bitten traditional news service. SUVs, which account for a big share of the excess consumption of fuel by U.S. consumer vehicles, present two safety issues: Their higher center of gravity makes them roll more easily, and their size gives drivers a false sense of confidence which makes them drive less safely. Researchers concluded, according to the Reuters story by Michael Kahn, that "lightweight, fuel efficient autos are safer for the driving public than the average sport utility vehicle."
