Any car with a built in GPS/ navigator has it now, and those have been moving down from the luxury cars very steadily the last 10 years.

I just took a peek inside my $130 suction cup GPS, and it was full of little packets like this one:

<trkpt lat="42.626619" lon="-70.978405">
    <ele>22.73</ele>
    <time>2012-07-08T17:14:22Z</time>
    <extensions>
        <gpxtpx:TrackPointExtension>
            <gpxtpx:speed>37.06</gpxtpx:speed>
            <gpxtpx:course>7.06</gpxtpx:course>
        </gpxtpx:TrackPointExtension>
    </extensions>
</trkpt>

Hint: speed is in meters / second.

Yup, cause that’s what you bought it for. Of course the ones that are built in are hooked up to the car computer, so they don’t have to figure out the speed they get it from the computer, they’re just adding GPS data to the pool that includes all kinds of awesome stuff like you fuel/ oxygen mix, whether or not you’re using your brakes, your seatbelt, tire pressure if you have self monitoring tires. This is the world we asked to live in.
