Speed limiters now mandatory in all new EU cars

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.
