Only AT 'walking speed' can a car stop if someone suddenly appears from between cars, etc
Car parks feature permanent architectural blind spots including concrete structural columns, tight corners, and rows of parked vehicles. These objects completely block sightlines. When a vehicle travels at 20 km/h, a driver covers 5.56 meters every second. Combining human perception delay and braking distance, it is physically and geometrically impossible for a driver traveling at 20 km/h to stop in time if a pedestrian steps out from behind a concrete pillar. True safety requires driving at strict walking speed (5 km/h) to maintain a near-zero stopping distance. Please leave comments on my initiative (then sign in 34 days).
