Samenvatting
Tables and charts of motor-vehicle stopping distances simply show distance required to stop by braking from various speeds under certain conditions. Differences among tables arise because different conditions are assumed. Most of the tables specify only in a general way what conditions the table represents. The user does not know that a car in "good condition on a level, dry, clean, concrete" roadway might have a drag factor as low as 0.44 or as high as 1,20 depending on circumstances which are not suggested in the table.
