In the question below, a statement is given depicting an issue or a problem. You have to assume everything in the statement to be true even if it is at variance from commonly known facts, and on the basis of the information given in the statement, decide which of the suggested courses of action logically follow(s) for pursuing. Statement : Several municipal transit authorities are testing high-speed, fully autonomous electric shuttle buses along busy downtown routes. Advocates highlight that these self-driving shuttles will significantly lower municipal transit costs and cut urban traffic congestion. However, urban transit planners and safety auditor groups have expressed major concerns regarding unpredictable pedestrian movements at busy intersections, potential sensor blind spots during heavy rain, and the current absence of municipal legal frameworks governing liability in autonomous vehicle collisions. Which of the following courses of action logically follow?
I. Roll out the autonomous shuttle fleet immediately across all transit corridors to maximize cost savings before public interest wanes.
II. Work jointly with municipal traffic boards and legal regulators to establish clear liability frameworks and speed-restricted autonomous transit zones.
III. Conduct phased trials in designated high-visibility, lower-density transit routes to validate sensor accuracy under varied weather conditions prior to full downtown integration.
