On rainy days or after rain, water is easy to accumulate on the road. After the vehicle stops, the vehicle is easy to be in a water accumulation position, making it impossible for passengers to get off the vehicle. In addition, most passengers in the car will not carefully lower their heads to observe the road conditions when getting off the vehicle. Passengers are likely to step on puddles or water accumulation, which will dirty their shoes and pants.
