[The elderly driver's perception of risk: do older drivers still express comparative optimism? ].

People frequently express comparative optimism ; that is, they believe they are less likely than average to experience negative events. The aim of the present study is, first, to observe whether people of more than 65 years are still optimists when they evaluate driving-related risks; and second, to test the assumption that older drivers show less optimism when they compare themselves with average-age drivers than when they compare themselves with same-age drivers. Our results reveal that drivers of more than 65 years do, indeed, express comparative optimism, but, contrary to our expectation, only in a limited number of cases does the age of the comparison target appear to have an effect. These results are particularly discussed in terms of self-image enhancement.
