Describe a scenario where an autonomous vehicle must make a decision to avoid a sudden obstacle. How should the vehicle's AI respond?

Instruction: Outline the decision-making process for an autonomous vehicle when encountering an unexpected obstacle.

Context: This question assesses the candidate's grasp of dynamic obstacle avoidance in autonomous driving. It evaluates the ability to prioritize safety and apply decision-making frameworks under unexpected conditions, reflecting on the critical thinking required for developing autonomous vehicle systems.

Example Answer

For sudden highway debris, I would assess the obstacle and surrounding traffic while accounting for perception delay, stopping distance, road friction and control limits. The planner should evaluate only feasible actions with uncertainty about adjacent vehicles. A reflexive swerve can create a worse collision, and braking may reduce harm without avoiding contact. I would not promise that AI always finds a safe escape. After the immediate response, verify vehicle state and follow the approved recovery or fallback procedure.

Make it your own

Illustrative simulation scenario: debris appears inside the available stopping distance while an adjacent lane is occupied. Compare braking and constrained steering outcomes without assuming either guarantees avoidance.

Why this works

The case makes physical limits explicit. This is an educational discussion, not an executable driving controller. Follow-up: what changes when the apparent open lane is partly occluded?
