Sacrificial anodes basically don't work on cars, and what little benefit they have experimentally shown in that use case is both very minimal and extremely situational.
The problem is that an electrical current has to flow directly from the sacrificial anode to the cathode body panels through the corrosive liquid, in addition to a physical connection through the frame. The very specific scenario in which they've shown to be effective in cars is when driving through large amounts of high-salinity water, like a really deep melty puddle on a salted road, where a significant portion of the car is actively wet. This is something that only really happens for a few moments at most, and only occasionally happens during a limited time period in only a portion of the world.
It's also less effective than simply using a phosphate underbody coating, so... Not really going to work.
Well at least you proved me right about not paying attention in science class lol
Given what you've said, I think there's a reasonable chance that Elon Musk and his team will respond to RustGate in 2024/2025 by offering a sacrifical anode as a "marine-grade" optional extra to get people who lack science literacy like me hyped up to shell out even more cash while Elon Musk can wink and nod to the camera over his ridiculous claims of how the Bladerunner's favourite car can also function as a boat "for short periods".
