Final answer:
The car was stationary on Edinburgh Street when it was hit, meaning it was parked. Light rain makes roads slippery due to oil, affecting driving control, while heavy rain may wash away some oil for better traction.
Step-by-step explanation:
The car in the scenario was stationary on Edinburgh Street when it was struck by another vehicle. This indicates that the car was parked and not moving at the time of impact. In terms of safety and road conditions, when there is a light rain, oil and gasoline on the road can make the surface slippery and more dangerous for driving, affecting the control of a car. A heavy rain may wash some of these substances away, potentially improving traction compared to conditions during a light rain.
