Hyundai and Kia cut costs by excluding industry standard engine immobilizers in their vehicles.

Most cars have a chip in the key, which is read by the car when you insert it into the keyhole, to verify the key is legit. Even if you cut a new copy of the key, the engine won’t start without that chip. That’s an engine immobilizer. It also prevents people from just brute-forcing the keyway into turning, with something like a screwdriver. Because again, no chip means the car won’t start.

Hyundai and Kia decided to forego these, as a cost cutting measure. And now those Hyundais and Kia’s are virtually worthless (and nearly impossible to insure,) because car thieves know how easy they are to steal. In the past few years, as the methods have gotten posted on places like YouTube and TikTok, anyone with a screwdriver can go steal a Hyundai or Kia. And theft rates have skyrocketed, to the point that some insurance companies are outright refusing to issue policies for them because they know it’ll eventually be stolen.

As for why it was referenced here, my guess is that they were making a parallel about how the technology to prevent spoofed phone numbers already exists. But the companies have decided not to implement them, as a cost-cutting (and anti-competition) measure.

Currently, some phone carriers already offer caller verification. But that only works for internal numbers. For instance, an AT&T caller dialing another AT&T phone. But the companies have refused to cooperate, and allow competitors to access their internal verification systems. So for instance, if an AT&T customer calls a T-Mobile customer, both AT&T and T-Mobile can verify internal calls. But neither company wants to play nice with the other, so they refuse to verify each others’ numbers. So when a spammer spoofs a number, any kind of verification would only be effective if the spammer has the same carrier as the target.
