Over the past few decades, there has been increasing "internetification" of everything. The Internet of Stings[1] has infected refrigerators, watches, televisions, and even light bulbs. As it turns out, shoehorning internet connected computer chips with proprietary[2] code into everything increases their attack surface making society more vulnerable to hacking groups[3], foreign governments and Big Brother.
Automobiles are no exception. They've also seen increased internetification. My own personal opinion is cars don't need wireless enabled computer chips, period. And I'm not the only[4] person[5] to think connected cars seem like a bad idea.
For this post, I want to focus on avoiding mass surveillance of automobiles. None of the recommendations in this post apply to work vehicles[6] or car rentals since you don't own those. This guide is only for your own personal vehicle.
My first piece of advice is don't buy a connected car. By connected car I mean a car with wireless capability other than radio. Buy an old car instead. Old cars predate the connected features of new cars. Ideally buy a car that doesn't support Wi-Fi, Bluetooth or cellular connections. If it has a touchscreen it's probably too new. If you need navigation, you can buy a cheap car phone mount and use your phone.
If you already own a connected car, the best advice I can give is to trade it in for an old car. Until then read the owner's manual and find out how to deactivate as many of the connected features as you can. Never pair your phone with your car. Disable Bluetooth and cellular connections on the car if possible.
Unfortunately even some old vehicles have remote diagnostics systems that collect and transmit vehicle sensor data wirelessly to the dealership, insurer, manufacturer or thugs[7]. I'll cover these by category starting with the dealership.
Automotive dealerships have GPS tracking devices[8] attached to cars primarily to prevent theft. When you buy a car, assume it has one and make the dealership agree to remove it as part of the terms of purchase before you buy the vehicle. Once you've bought the car from the dealership, there's no reason they need GPS tracking on it.
The exception of course is if you bought the car on a loan. Then either the dealership or the lender may require the GPS tracker on the car until it's fully paid for. In that case you can remove the GPS tracker yourself or have it removed after the car is fully paid for.
Car insurers promote remote telematics devices[9] to policyholders in exchange for lower rates. They use the OBD interface[10] in your vehicle to send real-time data to the insurer. Empowering Big Brother in exchange for cheaper rates isn't worth it. Don't let your insurer install tracking devices in your car. If your insurer requires them, find a new insurer.
General Motors includes OnStar[11] in its vehicles. OnStar is a telematics device capable of not only remotely surveilling GM vehicles, but also listening to live audio inside the car and remotely shutting the car down. Even if you don't have a subscription, OnStar can still track your GM vehicle. In fact they tracked vehicles that weren't even subscribed to OnStar services until they reversed the decision[12] due to public outcry from privacy advocates. Luckily there are plenty of guides online for how to remove OnStar[13] so they can't possibly track you.
SiriusXM also collects telematics. Unlike OnStar, there's no way to remove it I'm aware of. You can cancel your subscription, but SiriusXM can still collect telematics. The only solution is don't buy a vehicle that has telematics providers you can't remove.
Big Brother can also demand telematics information about your car from any of the above categories. This isn't theoretical. It happened with SiriusXM[14]. Thugs have used OnStar[15] several times to remotely shutdown car engines. ATX technologies[16] was forced to provide thugs with a live audio feed from inside a car.
Thugs are still allowed to put trackers on cars with a warrant. I'm not going to tell you how to spot covert thug GPS trackers. That's avoiding targeted surveillance which is out of the scope of this post. This post is only about avoiding mass automobile surveillance.
Onboard diagnostics systems (OBD) in vehicles were introduced in the 1980s. The USA, EU and other countries have mandated OBD-II[17] and EOBD[18] protocols for all vehicles sold.
If you have a gasoline engine and you're in the United States, OBD data is pulled from your vehicle when you get mandatory emissions testing unless you get standard tailpipe emissions testing done. To find out if you can get only standard tailpipe emissions testing, you'll have to call and ask local emissions testing sites and check state regulations.
If the emissions testing site uses proprietary OBD scanning software, then it's possible that your data gets collected and sold to insurance companies by the OBD software vendor. If the testing site uses a handheld OBD scanner, it's still possible that the data is eventually pulled off and sold if the handheld scanner connects to vendor software on an internet connected computer. The OBD-II interface has Mode $09 which retrieves uniquely identifiable information like the VIN number[19]. So if the OBD data does get sold, the data brokers know exactly whose vehicle it belongs to.
I've never heard of OBD data being involved in a data breach before. I don't have any information about what software is used by emissions testing sites. I'm just speculating. The only reason I have for thinking OBD data collection does happen at emissions testing sites through software vendors is because it can and it's profitable. Even if my speculation is true, you still have to get emissions testing done. I only mention emissions testing data collection for completeness and awareness, not because you can do anything besides political activism to prevent it.
When you take your car to a repair shop, one of the first things they're going to do is check the OBD-II interface for error codes. It's the same issue as before with emissions testing. The uniquely identifiable OBD data is exposed to potentially proprietary programs used by the car repair shop.
The difference is you don't have much choice in emissions testing. When it comes to auto repair, you have some choice. There are free software diagnostic tools for OBD-II[20] that don't collect and sell your data. You'll need an adapter[21] supported by your vehicle to use them. It's up to you to make sure the adapter will work before you buy it. If you want to repair your vehicle yourself, then that's the end of it.
If you need the auto repair shop to repair your vehicle, you can relay the results retrieved from your free software tools to them while requesting they don't use their own proprietary OBD scanning tools.
This section only applies to fully electric and hybrid cars. I've already made a post about networked EV charging stations[22]. Just so this post is self-contained, I'll reiterate:
There are two types of EV charging stations: networked and non-networked. The networked ones require you to sign up on the web with your real name, credit card information, address, and car make and model. You have to agree to the terms of service and privacy policy. After signing up, you receive a swipe card in the mail. Because you have to swipe an ID card to use networked charging stations, the network (Chargepoint) knows who you are, where you charged your car, when, and for how long. Non-networked charging stations don’t require you to use an ID card, so they can’t collect any personalized data on you.
Don't use the networked charging stations. Use the non-networked ones or just use your own charging cable instead.
Automatic license plate readers or ALPRs[23] are cameras that capture all license plate numbers that pass by. There isn't anything you can do about these besides political activism against them. Purposely obscuring your plates from these cameras might be illegal or cause you to get tickets. Even if there's nothing you can do, I still think it's important to be aware of ALPRs.
It may be possible to infer where you drive based on consumer surveillance alone. As a final piece of advice to further improve your vehicle's location privacy, follow the tips in my post on avoiding consumer surveillance[24].
When I make posts on how to avoid surveillance, what I'm trying to do is build resistance to tools of mass surveillance. At the end of the day there needs to be both technological and political changes to protect drivers' data. I offer temporary workarounds for avoiding surveillance until the dangerous trend of increased surveillance reverses itself. Society needs to start being proactive rather than reactive to corporate and government surveillance. I don't know when or how or if the trend of increased surveillance will be reversed, but I'll continue writing about ways to resist surveillance until I no longer need to.
At some point resisting mass surveillance becomes impractical. I understand my advice isn't always easy to follow. Choosing privacy can get expensive and time-consuming. And it's already hard enough to get people to use anti-surveillance tools that are easy to use, let alone follow a guide like this that requires lots of effort. Part of the function of these posts is to show the ridiculous lengths one must go for privacy in today's world. You don't have to follow all the steps in this guide. My practical advice is just do what you can. Remember, if all you do is cancel your insurance tracking, that's a win for privacy and a blow to Big Brother.
