Passage Summary: A letter writer argues that because death rates are going up in low-speed zones, the idea that low speed limits save lives is wrong, and we should actually raise the limits.

Conclusion: Speed limits should be increased to improve safety.

Reasoning: The current evidence shows that vehicle-related fatality rates are rising in areas where speed limits are lower.

Analysis: The author falls into a classic trap by confusing the direction of a trend with the absolute value of the data. Just because fatalities are 'rising' in low-speed areas doesn't mean they aren't still significantly lower than the fatality rates in high-speed areas. Furthermore, the author assumes that increasing speed limits would solve the problem without considering that doing so might make the rising fatality rates even worse. Look for an answer that identifies this failure to compare the relative safety of the two options.
