Electric cars are being developed into self-driving cars, where you input a destination, sit back, and enjoy the ride. It’s easy, it’s amazing; a comfort that people only imagined in the past. But in the back of your mind, a little voice asks: what if the car is reliant on software and connections and someone hacked in and took control?
Self-driving vehicles are not simply cars that can steer themselves. They’re computers on wheels, equipped with sensors, cameras, and an internet connection. Digital components continuously communicate with the core systems, providing real time instruction on the movement of the vehicle, obstacles, and the routes the vehicle should take. While such communication is essential to running vehicles optimally, it also brings the possibility of digital risks.
Technology that relies on software or components programmable by others carries risks. Modern cars connect to other devices via Wi-Fi, Bluetooth, or a cellular network. If any of those connections aren’t secure, there’s potential for someone to gain access to the system or the data stored inside. Even the smallest disturbance to the systems that communicate, or the data stored within, can lead to misinterpretation of the car’s response to its surroundings.
Manufacturers have long since started to regard cybersecurity with the same level of seriousness as mechanical safety. They engineer systems that can encrypt data, thwart unauthorised access, and identify unusual behaviour. Continued software updates can help close vulnerabilities before major issues arise. As vehicles become more sophisticated, hackers also have access to increasingly more sophisticated tools. Digital security is never complete; it requires ongoing management.
This isn’t just about preventing people from hijacking a vehicle. It’s also about privacy. Self-driving vehicles will undoubtedly collect and retain a colossal amount of data, such as trip routes, users’ voice commands, or users’ preferences. All of that must be protected as well.
Many drivers now manage parts of their car through mobile apps. They can unlock doors, start the engine, or check the battery from their phone. It’s convenient, but these apps often rely on shared or public networks when you’re out and about. That’s one reason why digital habits matter.
If you ever need to log into your car’s app on public Wi-Fi, using a private and encrypted connection can make a difference. A VPN service such as Surfshark, for example, helps protect your session, so your data cannot be easily intercepted while you manage vehicle settings online. It’s a small precaution that fits naturally into the same idea of keeping connected systems safe, whether you’re using a phone, a laptop, or a car that communicates with both.
While manufacturers build the main line of defence, drivers can add an extra layer of care:
Good habits may not sound exciting, but they make technology safer for everyone.
Self-driving cars will only become more common. Cities are preparing for them, and laws are being written to ensure digital safety is taken seriously. Engineers are already testing real-time monitoring systems that can recognise suspicious activity before it causes harm.
The goal isn’t to stop innovation, but to make it safer. As with seatbelts and airbags, security will become a standard part of the car’s design. The more data cars exchange, the stronger their protection will need to be.
Are self-driving vehicles vulnerable to hacking? The answer is yes; however, that risk can be mitigated. Self-driving car technology is impressive, yet it depends on the same technology and data we use in our world. Keeping those systems safe is no longer only a technical issue, but is part of being a responsible driver as we rely on more digital technology.
At the end of the day, the safest course forward is to follow the same suggestions for staying safe and secure in a connected car as we would advise for staying safe online: stay up to date, use trusted platforms, and think about the way in which your data moves around the web. The smarter vehicles become, the smarter we have to be about keeping them safe and secure.
