Show Several Reasons Why It Is Expensive to Speed The driver who persists In operating operat-ing his motor car at high speed may elude constables and police, says a writer in the Farm and Fireside, but he cannot escape from the penalties which natural mechanical laws levy upon his car. Here are ten reasons why it is expensive, dangerous and Inconsiderate of others to speed. Tires last about twice as long on a car that is driven at 15 miles an hour as upon cars driven at 30 miles an hour. Speeding generates heat, which is an enemy to rubber. Driving a car around a sharp corner at 2o miles an hour does more damage dam-age to the tires than 200 miles of straight road work. Excessive side pressure on tires may pinch the tubes, and it always strains the side walls of the casings. High speeds are likely to cause skidding skid-ding and breakage of springs and steering gear, any of which are dangerous dan-gerous when speeding. In proportion to the mileage obtained, ob-tained, high speeds require more gasoline gas-oline and oil than a moderate rate of traveling. . . ' i driving a car at excessive speed especially over rough roads, subjects the bearings to enormous strains. High speed may cause crystallization crystalliza-tion of rapidly moving metal parts that are subject to strain, and these may break at any time without warning. warn-ing. High speeds interfere with the accuracy ac-curacy of steering, as is shown by the number of reckless drivers who 'have gone over banks and into ditches especially es-pecially on curves. It Is a strain on the eyes and the nerves of the driver and also of the other passengers In the car. Finally, it is a menace 'to the pleasure pleas-ure and safety of others who use the road. The majority of modern motor cars develop their maximum efficiency with lowest expense at speeds ranging from lo to 25 miles an hour, depending on the make of car and conditions of the road. |
