The worry's a bit overblown if we're talking about your car actively transmitting video feeds to hackers right now, but the real issue is messier - it's less about dramatic surveillance and more about who owns your data once it leaves your vehicle. car makers and their partners (insurance companies, location services, advertisers) are collecting driving patterns, routes, and sometimes biometric data, and your agreement to their terms basically hands that over. what matters is whether you're comfortable with that trade-off, which depends on things like: do you use connected features like navigation or remote diagnostics, or would you rather have a less connected car? are you in a place where insurance companies use driving data for rates? if those sound fine to you, the risk is pretty low, but if you value privacy, you might want to check what your specific model collects before buying.
