An adequate space margin is one that provides a driver with: All of the above; (space, time, visibility), Graduated Driver License Programs generally involve _____ stages. Two. Car 1, travelling at 65 km/h, is overtaking Car 2, which is travelling at 60 km/h. Thus, the impact occurs at about 30 kilometres/hour, probably fast enough to kill Sam. Because the pedestrian, Sam, is so much lighter than the car, he has little effect upon its speed. For example, if a car doubles its speed from 30 mph to 60 mph, the thinking distance will double from 9 m to 18 m and the braking distance will increase by a factor of four from 14 m to 56 m .
