Exactly this happened to my father last fall with a Audi Q1. It finally turned out to be a electronics issue, but the car was limiting itself to very low max speeds (40 kmh or so, which legally disallowed my father from using the Autobahn).

With a car the obvious answer is: get the thing checked immidiately. He did, and he still had to drive around like this for 2 weeks till a replacement part arrived.

I don’t realize that. It happens all the time. There are many services dedicated to helping stranded people because of it.

The analogy is not quite right though. It’s more like they are forcibly reducing max speed to prevent a high speed stall.

Cars break. They don't rate limit you. Please share with me a model of vehicle that reduces your max speed because you're low on gas.

Thanks. I still think this is more of the exception than the rule, but I do stand corrected.
