<p>The accelerometer comprises: an accelerometer chip (7,fig4); a display interface 3 adapted to display to the driver of the vehicle while driving an indication of net acceleration force perceived by the accelerometer chip in the medial plane of the vehicle at least in magnitude, and optionally also in direction fore-and-aft and/or left-and-right. The display interface includes an indicator, concentric rings (9, fig 2), defining a datum position and adapted to provide an indication of the magnitude of net perceived acceleration force by the extent from said datum position that successive regions of the indicator are lit or subject to a colour change. The indicator is coupled to circuitry linked to the accelerometer chip.</p> |
