Solution Steps

Step 1: Calculate the Actual Number of Respondents

To find the actual number of respondents who rated themselves as above average drivers, we use the formula:

\[ \text{Number of respondents} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Total respondents} \]

Substituting the given values:

\[ \text{Number of respondents} = \left( \frac{62}{100} \right) \times 1114 = 0.62 \times 1114 = 691.68 \]

Rounding to the nearest whole number, we find:

\[ \text{Actual number of respondents} = 691 \]

Final Answer

The actual number of respondents who rated themselves as above average drivers is \\(\boxed{691}\\).
