With regard to the letter by Vaucher et al., it should be stressed that neither the premise of our study nor our conclusions are reflected correctly in this comment. As described in our paper, it is not intended to use solely a saccadic eye test to make a final decision on the ability to drive. However, our study indicates that such a test can be helpful as a screening tool, i.e. as a first step determinant to pre-select individuals who are likely to perform poorly as a driver and thus need a more detailed assessment. Given the high number of examinations that can be expected owing to our aging population, we believe that efficient and reliable test procedures are necessary to assess the ability to drive.
