You are a lead AI ethicist at a major autonomous vehicle manufacturer. Design a weighted ethical decision matrix for an AI driver facing a 'Trolley Problem' scenario. The vehicle must choose between swerving into a barrier (high risk of passenger death) or continuing forward (high risk of pedestrian deaths). Your response must define the variables, assign weights based on Utilitarian and Deontological frameworks, and explain how the system handles uncertainty regarding sensor data. Provide pseudocode for the final decision logic.
