I'm experimenting with the BMW Java SDK on the new BMW 116i Innovation Package. Basic things like turning the lights on and off, starting and stopping the motor work fine. What I'm trying to do now is that to write a carlet which would limit the speed to the maximum configured in the driver profile. Driver identity will be detected as usual via RFID reader.

My problem is that though I can read the speed from the tachometer, I can't really limit the speed. Here's what I've got working so far:

public class SpeenControllingCarlet extends GenericCarlet {

    public void start(final VehicleModel model) throws CarletException {
        RfidReader rfidReader = (RfidReader) model
                .getDevice(Devices.DRIVER_RFID_READER);
        Rfid rfid = rfidReader.getRfid();
        DriverProfile driverProfile = model.getDriverProfileRegistry()
                .getDriverProfile(rfid.toString());
        if (driverProfile == null) {
            return;
        }
        final Double maxAllowedSpeed = Double.valueOf(driverProfile
                .getCustomAttribute("maxAllowedSpeed", "190"));
        Tachometer tachometer = (Tachometer) mode.getDevice(Devices.TACHOMETER);
        tachometer.addSpeedListener(new SpeedListener() {
            public void onSpeedChanged(SpeedChangedEvent speedChangedEvent) {
                if (speedChangedEvent.getCurrentSpeed() > maxAllowedSpeed)
                {
                    Horn horn = (Horn) mode.getDevice(Devices.HORN);
                    horn.beep(440, 2000);
                }

            }
        });
    }
}

This will just beep for two seconds if the driver goes faster than the driver profile allows.

My question is - is there a possibility to actually limit the speed (not just silly beeping)?
