Abstract or Description

We can be too safe; Achieving' safety costs us time and other scarce resources. For example, if all transportation-vehicles were restricted to speeds of one mile per hour, there would be a marked: decrease in the accident rate, but few people would find they were better off than they are at present. A good transportation mode is one that gets me to my destination quickly, cheaply, and safely. In general, one attribute can be bettered only by worsening another-that is, additional safety is available only by trading for it higher cost or slower speed.
