Reverse-Engineer Why a Car Would Carry a Hood-Mounted Mirror

Some cars are built with a mirror mounted on the bonnet (the hood). Why would the designers put a mirror there? ```hint Start from what the driver cannot see List what the driver cannot see, or can see only by looking away from the road, and which drivers and vehicles have that problem worst. Then ask what a mirror in that exact spot offers that a door mirror does not, and what it gives up. ``` ### Clarifying Questions - Is the mirror on the front corner of the bonnet or fender, angled back like a side mirror, or is it aimed down at the ground just ahead of the bumper? - What kind of vehicle is it: a taxi or ordinary passenger car, or a tall SUV or truck with a high hood? - Does it replace the door mirrors or supplement them? - Should I explain only why the design exists, or also whether it still makes sense now that cameras and blind-spot sensors are common? ### What a Strong Answer Covers - The drivers involved, their jobs on the road and the specific visibility gaps those jobs expose - Why a mirror at that position helps, explained through where the driver looks and what the car's body hides, and what the position costs - A comparison with door mirrors, convex mirrors, cameras and sensors on cost, reliability, safety and regulation - How the reasoning would be tested with evidence, and what the car's designers should do today ### Follow-up Questions - If you were the product manager for this car today, would you keep the bonnet mirror or replace it with a camera? What evidence would decide it? - Passenger cars in most markets use door mirrors rather than bonnet-mounted ones. What user needs or constraints explain that shift? - How would you measure whether the mirror actually prevents collisions?
