    You need location data to be able to determine what limit to impose.

    And I bet you anything it will be a cloud based system.

      You don’t, just just need localized broadcast and a receiver in the car. Or cameras and signs as other people have mentioned.

        They don’t transmit the speed limit of the current road, and for things like construction they’ll need real-time updates.

        I’m certain they won’t want to push the entire database out to every vehicle for every update…

          I have a hard time believing it would be impossible to wire up a device that sends out a wireless signal with the local speed limit at every speed limit sign.

          Why does it need to go to a database for it instead of have a receiver on the vehicle itself to pull data as it passes speed limit signs?

          In fact, a centralized database would likely have more problems with not being accurate or current. Have you ever dealt with government databases?

          Edit: Part of the reason the database would be trash is because speed limits are set by cities, not by the state. So in the database scenario every time a city updates their speed limit, they have to document all the zones and upload them to the database. All it takes is paperwork getting backed up a week for that to cause problems.

            The problem with proposing infrastructure is that people hate it. Even if it would be beneficial. Train traffic is limited to 79 mph in the US because the companies in charge were told “put in more safety devices or you’re limited to 79 mph”, and they said “okay sure”.

            They usually act like anything that wasn’t around when they were born is impossible. I can’t imagine trying to get a smoking ban passed now, or capping the national speed limit at 55 because of an oil crisis.

              We got a tough guy here.

              EDIT: Also I’m fairly sure that destruction of government property is a felony and if it’s wired for this, it could easily be wired to take and send photos when tampered with, but you do you. I guess people do just hate infrastructure more than *checks notes… being spied on. Because when given an alternative without a database, they shit on it.

                i don’t think they’d spend the money to add cameras too for every sign, when you can just put on a mask for them. i was half joking but yeah, i would definitely prefer not to have transmitters control the speed of my car

            Generally temporary speed limit changes just go down, so the worst case is for a little while your car will let you speed. And if it goes up but the town fucks up and doesn’t update the database, people will complain while being forced to drive a little slower than the new maximum.

          They don’t need real time updates to accomplish their goals. The car just needs accurate days most of the time. Having the car download periodic updates to a database that covers the whole state is perfectly feasible and involves no tracking.

          You should be worried more about tracking through license plates and cameras.

          It would work everywhere except construction sites, where we can just have cops like we do everywhere right now.

          GPS is a great solution, it already tells you what the speed limits are depending on the software.
