Changes in Traffic Jams and Injuries Impact on Acceptability of Automated Vehicles: A Strong Curvilinear Relation with no signs of Loss Aversion.

We investigate whether the acceptance of autonomous trucks as a function of their impact on traffic jams and injury rates are affected by loss aversion and diminishing sensitivity as described in prospect theory. In an online survey (N = 447), we presented randomised sets of values the replacement of human truck drivers would have on traffic jams and injuries. Adjusting for loss aversion provides no additional explained variance in the model, but adjusting for diminishing sensitivity does.
