No, it's not a mistake.
Electronics is a large field, quite a few concepts can be niche and unfamiliar even to its practitioners, so please don't assume something is incorrect just because you personally have never heard about it. I recommend doing a quick search first before trying to refute anyone. Here are just two examples I've came across recently:
1. Someone asked a question about a "DC-link" capacitor. One experienced engineer replied and claimed it's nonsense, because DC cannot pass through a capacitor. But in fact, it's a standard term in the power inverter industry that refers to the capacitors between an AC/DC and DC/AC power stage.
2. An article about Ethernet "magnetics". A reader replied and claimed the term "magnetics" is nonsense because they've never heard of it, if it's a transformer, just call it a transformer! But in fact, it's a standard term in Ethernet hardware that refers to both the isolation transformer and the optional common-mode choke at an Ethernet port. To a lesser degree, it's also valid in the power supply industry as a collective term for the magnetic components like inductors, EMI chokes, and transformers.

High-speed, Gbps-level digital link solutions for automotive applications are currently being heavily promoted by semiconductor companies, it started since a few years ago. This is something you can immediately know just by a casual browsing of their websites and take a look of their latest chips, like Analog, Maxim, or TI. I assume this interest first came from the demand side, by the OEMs. You don't just make these chips for nothing.
One major application is the transmission of HD videos in a car entertainment system.
> Some newer forms of automotive networking used here and there for a time, but OEMs keep trying them, ditching them, and returning to slow networking.
You may be correct. This can be another attempt at it, and may or may not be ultimately successful.
