A true Human Factors pioneer in action...
Clearly beyond the days of covered wagons, but in the mid 1960's pioneering research was being conducted on the attentional demands of automobile driving.
This work did not require a private racetrack or even approval from your local Institutional Review Board (IRB). All it required was some mechanical ingenuity, a few relay boxes, a slightly modified 1965 Dodge Polara, and I-495 outside of Boston. Although the Buck Rogers' style lighting bolt on the helmet shows that not all was taken seriously, serious pioneering research was being conducted. Professor John W. Senders (shown in the video and photos) controls the amount of time that the visor of the helmet is down. While down, the sand-blasted visor allows in light, but no details; not even the shadow of large trucks coming at you from the wrong lane. The empirical component of Senders' research was conducted to confirm the predictions of his Control Theory-based models.
