          <div>There's an average speed limit section in Canberra near
            Woden too but no one has added that to the map yet so I
            couldn't copy. Any other examples I could refer to?</div>
          <div><br>
          </div>
          <div>Unfortunately I've had to use "maxspeed" as the
            enforcement type even though you could do 200 km/h while in
            the enforcement area and then pull over and wait for 10
            minutes and not get booked.</div>
          <div><br>
          </div>
          <div>
            <div>It appears you shouldn't include the highway way in the
              relation just the nodes so I've created the two camera
              devices and attached them to nodes of the highway using a
              relation and the roles to, from and device.</div>

    <br>
    The enforcement would only be in one direction.<br>
    <br>
    The relation 'only' requires one 'device' though in practice here
    two are used. <br>
    <br>
    So it looks fine to me. <br>
    <br>
    overpass turbo can be used to find other relations of this type,
    there are a few around Sydney , Melbourne and one around Albury. <br>

    So a minimum time of 10 minutes 27.07 seconds.<br>
    At 220 km/h average speed you would need to pull over and wait some
    5 minutes 13.04 seconds to be 'safe' (from a fine). <br>
