Intelligent Speed Assitance (ISA) systems became a legal requirement for motors across the EU as a law passed two years ago came into effect on July 7.
ISAs make use of AI, GPS data and even onboard cameras to assess your speed in real time as you drive along.
The system will then intervene if you go above the limit it has worked out for the road you are on.
For example, the system can assess things like road markings to determine whether you are in a 20mph or 30mph zone.
with each offering different levels of intervention.
First of all, informative ISAs only result in a warning message and sound to alert the driver that they are breaking the limit.
One level up from that is the supportive ISA, which works by increasing the upward force on the accelerator pedal to try and make it harder for drivers to speed up.
Finally, intervening ISAs are the most active, with the system actually slowing the vehicle down, whether the driver wants it to or not, until it goes back under the limit.
Here are the top political news stories for today.
