SPEED DEVIATION INDICATOR
First Claim
1. ) A speed deviation indication apparatus for use in a motor vehicle, the apparatus comprising:
- a) a data input for receiving a description of a prevailing speed of the motor vehicle;
b) an electronic memory for storing a non-zero reference speed \andc) a user output interface operative to present, in a driver cone of sight defined by the motor vehicle, a visual signal of an intensity of at least 2000 minicandles indicating a speed difference between;
i) a subsequent speed of the motor vehicle as received via said data input; and
ii) said established non-zero reference speed.

Abstract
Apparatus and methods for indicating speed deviations of a motor vehicle are disclosed herein. In some embodiments, upon a user engagement of a user input interface (for example, a button or dial or any other input device), a reference speed of the motor vehicle is desired. Indications of subsequent speed deviations from the reference speed are provided, for example, in a non-numerical or non-textual visual signal having a luminous intensity of at least 2000 minicandles, in a driver cone of sight defined by the motor vehicle. In some embodiments, the visual signal indicates which of three ranges of speed the driver is driving in, including too fast, too slow and a mid range.

8. ) A method of manufacturing comprising:
a) deploying in a motor vehicle; i) a data input for receiving a description of a prevailing speed of the motor vehicle; ii) a user input interface for establishing, in accordance with a user engagement of said user input interface, a non-zero reference speed determined by a prevailing said received prevailing speed at or near a time of said user engagement; and ii) a user output interface operative to present, in a driver cone of sight defined by the motor vehicle, a visual signal of intensity of at least 2000 minicandles indicating a speed difference between; A) a subsequent speed of the motor vehicle as received via said data input; and B) said established non-zero reference speed.
