“The latest versions of these GPS systems have ‘real time’ functionality. They can adjust route guidance to take account of accidents along your planned route, for instance. This is handy. But the same functionality can be put to other uses, too. For instance, there is no technological reason why the new Lincoln MKZ’s ability to keep abreast of the speed limit wherever you happen to be driving could not also be used to limit the speed you drive – or at least, record your failure to abide by the speed limit and perhaps report your noncompliance to the authorities. Or more likely, your insurance company. Perhaps both.”
