We have often spoken of the "flaws" in public policies and regulatory frameworks of states or cities as so many opportunities for imaginative entrepreneurs to create disruptive businesses (think of Airbnb or Uber for example). But the flip side is that much often, these same public policies do not keep pace with the increasingly rapid pace of changing technological innovations or business models in such a way that they constitute a constraint or even a brake on their development. Imagine, just a little, the spaghetti of regulations of all kinds, from local, regional or national authorities, faced by those who want to test, in the public space, a prototype of an autonomous vehicle, for example, in an urban environment. Hell! Our three panelists have had to deal or are currently dealing with this type of context and will share their observations, the lessons they have learned from them as well as some possible solutions, both for those who want to innovate and for public decision-makers.
