You cannot cross the street in front of a nearby vehicle, because it will not have time to slow down. Any transport, even the lightest, has a stopping distance due to the inertia of the traffic. The inertia is the stronger, the higher the speed of the transport and the more it weighs. A passenger car traveling at a speed of 20 km / h will have a much shorter braking distance than a KAMAZ traveling at a speed of 100 km / h, but this braking distance will not be short enough so as not to knock a person running across the road in front of the car. In such cases, drivers can turn sharply so as not to run over a person, but this is fraught with accidents in which many people can die. Therefore, you should never cross the street directly in front of cars.
