As autonomous drive development marches forward and collaboration accelerates, a new need is emerging: a language that can standardize descriptions of driving scenarios. Not only is such a language important for inter- and intra-team collaboration, but it will someday make it possible for regulators to develop a "driver's test" for self-driving cars. Jon Mullen, CTO of the simulation company Righthook, recently created an open scenario language for precisely these reasons and joins MergeNow to discuss his creation and its applications.
