The familiarity with the car used in the experiment would be an extraneous variable because it is not the main variable being studied (the effect of using cell phones while driving on the likelihood of having an accident) but could potentially affect the outcome. It is not independent because it is not being manipulated by the researcher and it is not a control variable because it is not being used as a baseline for comparison. It is also not a dependent variable because it is not being measured in relation to the main variable.
