Science: A Tell-Tale Speedometer

” Every speeder his own judge ” is the novel means which the Swedish Riksdag, with the help of inventors, has adopted to curb reckless auto-mobiling. Experiments are being conducted with a new recording speedometer which is to indicate not only the number of miles a car has run, but also the rate of speed during any part of the trip. Despite the fact that no recording speedometer has been perfected, the new law makes it compulsory for every car to carry one. This automatic evidence will both acquit the innocent and convict the guilty.
