EU mandates the alcohol detector in every car

The European Union is requiring an alcohol interlock system in new cars by 2027. The device checks your breath before the engine will start — if you've been drinking, the car won't move. It's the first EU-wide mandate of this kind.

The technology isn't new. France has been installing these units in rental cars since 2009, and the UK mandates them for repeat DUI offenders. What's different is the scale: every new passenger vehicle sold in the EU gets one. The Commission says it will cut alcohol-related fatalities by 40 percent, drawing on data from countries that already run the program.

The hardware lives in the steering column and draws power from the car's electrical system. It doesn't connect to the internet — no GPS, no cloud, no data harvesting. The only thing it does is read your breath and refuse to start the ignition if the alcohol level is above the legal limit. You can still drive after drinking; you just have to wait until you sober up.

Why this matters for us: this is how policy actually works — a small device, no data collection, a clear rule enforced by the machine itself, not by a police officer on a roadside. The EU is doing for drunk driving what seatbelt laws did for crashes, and the tech is quiet enough that nobody's building a surveillance state out of it.
