The EU is exploring satellite-enforced speed limits, but there is no official plan to mandate them yet.
Current ISA systems already misread speed limits, which becomes a bigger issue if cars can slow themselves down.
Public backlash could be strong if the EU officially announces these new speed limits.
The Intelligent Speed Assistance (ISA) system is mandatory on all cars sold in the European Union. It displays the speed limit, emits a sound if you go over, and adjusts your speed on cruise control. But the EU wants to go further by mandating that all cars sold after 2030 have a satellite-enforced speed limit, The Daily Mail reported last week.
The proposal reportedly under consideration aims to go beyond simply having the car tell you the speed limit. Instead of simply warning drivers, the system could use satellite positioning and onboard sensors to determine the car's location, compare it with the local speed limit, and reduce power if the driver is speeding.
