EU proposes automatic speed‑limiting system for new cars by 2030

The European Commission is considering a regulation that would require new vehicles sold in the EU to be equipped with an automatic speed‑limiting function capable of braking the car when the driver exceeds the posted speed limit. The measure would build on the existing Intelligent Speed Assistance (ISA) system, which has been mandatory for new cars since July 2024 and currently only provides warnings or mild interventions that the driver can override. Under the proposal, the car could actively reduce speed by applying the brakes without driver input. The Commission has not yet decided whether the rule will be adopted.

Critics, including automotive journalist Coen Grutters, argue the technology is not yet reliable and raise concerns about driver autonomy. Supporters claim it could improve road safety. Earlier trials in New York city showed that active speed‑limiting led 99 % of drivers to stay within speed limits and reduced harsh braking events, but practical performance in broader contexts remains debated.
