You start in a delivery van parked on a city street. Before touching the wheel, you fasten your seat belt and clear the cab: a pizza box blocking your view, a water bottle that could roll under the brake pedal, loose parcels. Then you check the right side mirror and pull out within seconds, a habit trained on every stop and start. In the city center, you flag the car ahead when it brakes sharply, a motorcyclist weaving between lanes and pedestrians at the crosswalks. Meanwhile a party bus, a roadside accident, calls from your supervisor and HR, a beeping GPS and a loud radio all compete for your attention. Look away for more than four seconds, and you see the collision that follows. At the end, you get a summary of identified hazards, missed hazards and false alarms, with a score from 0 to 100.
