Driving while blinding self with helmet

This video shows a man driving an automobile down a major highway while a helmet repeatedly flaps shut, blinding him. It documents the experiment described in “The attentional demand of automobile driving” [Senders, J. W., Kristofferson, A. B., Levison, W. H., Dietrich, C. W., & Ward, J. L., Highway Research Record, vol. 195, 1967, pp. 15-33]. (Thanks to investigator Gary Dryfoos for bringing it to our attention.)
