Abstract

In their analysis of controversial policies, van Wee et al. (2023) called for more ex-post analyses of new transport policies and that is what is offered here with a case study of the nature and effects of online mis(dis)information on the new national default speed limit of 20mph in Wales. High levels of opposition were observed in Wales during and post-launch. Possible underlying reasons for these protests are discussed. The protests had a dramatic effect, with the speed limit change becoming an unexpected ‘cause-celebre’ on both sides of the political divide. The findings of one exploratory case study should be interpreted with caution, however, in the context of rising international trends of the use of online persuasion techniques by campaigners and politicians, it is hoped that the in-depth exploration of what happened in Wales and why it happened is helpful. If the Wales 20mph policy launch is indicative of the power of online activism in potentially de-stabilising new transport initiatives, then policy makers and delivery professionals in future need to plan accordingly. Suggestions are made for policies that would help mitigate the effects of the type of mis/disinformation seen here.
