Tech-industry experts, city planners and even Gov. Jay Inslee have touted self-driving cars as a panacea, cutting congestion and vehicle emissions while reducing collisions.
But an announcement last month from Amazon's self-driving car unit Zoox that it will soon start testing its autonomous vehicles in downtown Seattle drew criticism from transportation-safety advocates. The early promise of the technology, they said, has been overshadowed by a string of crashes and near-misses, due in part to lax oversight of the rapidly growing sector.
