      Those are fixed speed governors for fleet fuel economy and/or manufacturer choice to prevent operators from turning their engine block into something externally ventilated. Not variable governors that require knowledge of where the car is to adapt to the local speed limit, a significantly more complex challenge, and one with a solution that is inherently insecure, privacy-violating, and almost guaranteed to instantly be abused.

        Do you think GPS units are broadcasting their location to know where they are? They just download maps and use the signal to localize themselves. Too many people acting like they know how tech works without understanding the basics of the largely non-networked world that existed before smartphones and spyware apps absorbed every feature.

      Yes, but speed limits change. There’s no way of reliably knowing what the current speed limit is without wireless communication.

        As someone with an Audi that will adjust your cruise control automatically based on speed limit (or rather what it thinks the speed limit is) I couldn’t be more against this. I had to disable the feature after multiple times where it thought I was on some 15mph ramp rather than the freeway and slammed on the brakes in the middle of traffic going 70mph.

          VW and BYD as well, but VW has been the most accurate I have driven. Even with that I would say at best 80% accurate on what the speed limit is.
