Prien. … You can get a crude idea of what is involved in a “driving past the driveway” study using a sheet of paper, a ruler, a sharp pencil and a protractor. ……… Lay the paper lengthwise. Use the ruler to draw two parallel lines from top to bottom one-inch apart. This is Rockingham. The vertical line on the right is the Rockingham curb next to where O.J.’s Bronco was parked on a 2-degree angle. Use the protractor to draw the angle with the starting point of the angle at the upper tip of the curb (the right line). Extend the 2-degree angle line as far down as it will go. The picture you get should show three lines. The one on the left represents the curb on the opposite side of the street from O.J.’s house. The one on the right represents the curb next to where the Bronco was parked. The third line should give you a long, narrow wedge with a point at the top and a quarter of an inch separation at the bottom from the right-hand curb line. ……….. The Bronco going north (toward the top of the paper) would have to be moving parallel to the curb at a variable range of speeds. The right tires could be closer or farther away from the curb than the end point on the angled line indicates. To proceed to the next step, you have to know the actual width of the street. With the width of the street you can scale the Bronco to its proportionate dimensions and begin the study using variables of speed, distance from curb, obstacle locations and obstacle avoidance maneuvers. ……….. If you do only this much, you don’t have to go much further because you can see where the Bronco had to make one turn to be in line with the 2-degree angle. If a vehicle were parked along this path (a vehicle did block this path when Park took O.J. to the airport), the Bronco would have had to make two turns to get around it and end up in the right zone at a 2-degree angle. ………. Could this have happened by chance? Sure. But what are the odds given the “infinite variables”? –Jasper
