One problem with big-city driving, as you point out, is restricted driver vision due to building placement. This has the effect of sometimes placing the point of no return (you are going to hit someone or something) before the point of possible perception, in other words, it's hopeless.Another factor, which rate of speed only partially mitigates, is what actually happens to pedestrians when they are struck by vehicles. For cars, pedestrians often sustain "bumper fractures" to their legs, and then go up and over the front hood, sometimes hitting the windshield or being flung high into the air. For trucks, beese, and some larger SUVs, the pedestrian goes down under the vehicle, sometimes getting run over by the wheels. The energy being transferred to the pedestrian is a function of both speed and them mass of the vehicle, but I've seen patients get critically injured in parking garages. At low speeds, you get that slow, twisting, grinding kind f injury, which is why I say speed only partially mitigates the effects on the pedestrian. It is true that speed does make a life-or-death difference. |
