Pre and post survey data for the Echelon cycling safety video.

Data collected through Qualtrics using participants recruited through Prolific to test the effect of a cycling safety intervention video aimed at drivers. Measures comprised explicit attitude towards cyclists, intended lateral clearance when overtaking cyclists and implicit attitude, using the Implicit Association Test (IAT). The IAT was built in Qualtircs and analysed using the IAT-gen tool (Carpenter, T.P., Pogacar, R., Pullig, C., Kouril, M., Aguilar, S., LaBouff, J., Isenberg, N. and Chakroff, A., 2019.
