The Day Your Car Decided to Start Sending Letters

Somewhere in a data centre you'll never visit, your car is having a conversation. It started the moment you drove off the forecourt, and depending on what you agreed to, which is to say, depending on whether you read seventeen pages of telematics terms in the showroom while a salesman hovered, you probably don't know what it's saying.

Your Car Is a Networked Device

Most new cars sold in the UK in the last five or so years are, under the skin, networked devices. Not in a vague, futuristic sense. Right now. A SIM card, usually embedded at the factory, is quietly reporting your location, your speed history, whether your brakes need attention, and occasionally whether your seatbelt is on. This data goes to the manufacturer. Some of it feeds the live traffic rerouting your sat-nav does so impressively. Some goes to algorithms you've never met. A small amount – if you've opted into certain features – goes to your insurance company.

Car with mailbox attached — detail

None of which is necessarily sinister. But here's the part most buyers never quite clock: a lot of these features are running on a clock.

The Trial Period, and What Follows

Manufacturers typically bundle connected services into a trial period, one to three years is common, after which they switch to a paid subscription. The traffic data, the remote door locking via your phone, the "vehicle health" pings that tell you when something's about to give up – these are not features you bought. They are features you are borrowing, for now, for free. The car you drove home is not quite the same car you'll be driving in three years, unless you keep paying. This is the same mechanic as a streaming service cancelling your favourites the moment you stop subscribing, except the thing being cancelled is a bit of your car. You can read more about exactly how this subscription layer works in The Subscription Service You Signed Up For When You Bought a Car.

Does car telematics data get shared with insurers?

The stranger question is what the data trail actually looks like once it's out there. Manufacturers are coy about specifics, which is understandable, but what's known is this: your driving patterns, your home address (inferred from where the car sits overnight), and your acceleration habits are all commercially interesting to third parties. Some manufacturers have already begun selling anonymised driving data to insurers and mapping companies. "Anonymised" does a lot of lifting as a word – given that a car parked on the same driveway every night is not enormously difficult to attribute to a person.

What You Actually Signed

The honest version of what happened when you signed the purchase agreement is something like: you bought a vehicle, and a connected-services company quietly leased you a layer of features on top of it. The car belongs to you. Or to your finance agreement, which is its own conversation. The data the car generates belongs, in most cases, to someone else entirely.

That's the arrangement. Not a scandal, not a conspiracy – just a thing worth knowing about the object sitting on your drive, humming quietly to itself.

Questions this raises

  • Can you switch off the SIM card in your car?
  • How do you find out what your car records?
  • Is connected car data covered by UK GDPR?
