DRIVING HABIT MONITOR AND SENSOR THEREFOR ABSTRACT OF THE DISCLOSURE The disclosure goes beyond prior art that shows G-level sensors which merely actuate warning bells, etc., in that the display is of the number of excesses of G-level per unit time. According to the invention, the rate at which a person exceeds a pre-set limit of G-level is a measure of the violence of his driving. Besides this novel form of display or presentation, a novel G-level sensor is disclosed. The sensor comprises a short length of polyethylene tubing, sealed with polyethylene plugs and containing a blob of mercury. The tube is bent over a saddle to provide a central curved portion and two straight arms. Wires are pushed through the walls of the tube near the ends of the arms, to act as electrical contacts. The disposition of the sensor is such as to virtually ensure freedom from spurious signals due to sloshing of the mercury, by using the mercury's own surface tension.
