Speed limiters now mandatory in all new EU cars

Original Article ↗ Hacker News Discussion ↗

New EU rules mandating Intelligent Speed Assist in all new cars are polarizing drivers and technologists alike. Supporters expect fewer crashes and lower pedestrian fatalities as vehicles warn or gently slow drivers who exceed posted limits, arguing it’s consistent with how scooters and e‑bikes are already regulated. Critics counter that current sign‑ and GPS‑based systems are error‑prone, may create dangerous speed differentials and false braking, and expand the potential for surveillance or overregulation, especially before road design and driver training issues are addressed.

What the EU Rule Actually Requires

  • Mandates “Intelligent Speed Assistance” (ISA) on all new vehicles, but only as a feature that must be present.
  • Systems may:
    • Warn acoustically or via vibration,
    • Add haptic resistance to the accelerator,
    • Or gently reduce speed — but this can be overridden by pressing the pedal harder.
  • Currently, activation is not legally required; in practice many cars let drivers disable it (often per trip).

Technology & Reliability Concerns

  • Many report incorrect speed detection:
    • Misreading construction-zone signs, exits, or adjacent roads.
    • GPS confusion between main roads, side roads, bridges, and tunnels.
    • Old databases that ignore changed limits.
  • These errors can cause incessant beeping, phantom braking, and higher cognitive load, especially in complex environments.
  • Several argue the tech is “fantasy” at policy scale; others counter that ISA has run in real-world pilots and already exists in many cars.

Safety, Speed, and Passing

  • Pro-ISA side:
    • Speed is strongly linked to crash severity, particularly for pedestrians and cyclists; injury risk rises nonlinearly with impact speed.
    • Treats small, habitual speeding (5–10 mph/km/h over) as a serious risk, not a harmless norm.
  • Skeptical side:
    • Claim speed differential and poor road design matter more than absolute speed in many crashes.
    • Worry that being stuck at the limit in traffic flowing faster creates hazards.
    • Argue that temporary speeding is sometimes needed for overtaking, especially on two‑lane roads and around slow trucks.
    • Note mixed empirical narratives: Autobahn vs U.S. highways, Germany’s A24 example, and confounding factors (driver training, vehicle tech, post‑COVID trends).

Privacy, “Pre‑Crime,” and Control

  • Strong concern over surveillance potential: location‑aware speed enforcement tied to identifiable vehicles could evolve into pervasive tracking or “social credit”‑style systems.
  • Some view this as a broader trend of cars becoming networked, data‑harvesting devices; right‑to‑repair and “rooted cars” are raised as counters.
  • Others respond that ISA need not report data centrally and that current threats (connected-car telematics, ALPR) are already worse.

Policy Alternatives & Broader Impacts

  • Alternatives suggested:
    • More speed cameras and higher fines (e.g., France).
    • Physical traffic calming (narrowings, curves, speed bumps).
    • Simple global governors (e.g., cap at 90–110 mph) instead of dynamic ISA.
  • Fears of:
    • “Nanny state” overreach and unelected regulators.
    • Uneven traffic flow as only new cars are constrained.
    • Incentives to keep older, non‑limited cars longer or to hack/remove ISA.
