By 2022, new cars produced in the EU will only come off the production line after being equipped with a series of intelligent systems to prevent accidents. These include Intelligent Speed Adaptation (ISA) systems, which read speed limits (and/or obtain the relevant information from navigation systems), or so-called Speed Limit (Information) systems, which inform about the maximum permitted speed and, if necessary, limit the speed of the vehicle upwards (at a certain speed, no further increase is permitted).
In principle, one differentiates between intervening systems and (only) assisting systems. What makes ISA systems preferable to pure speed limiters (or speed limit information systems) is the technical detail of adapting the top speed to the local speed limit, by reducing engine power.
