Bind Engine action to User Action 1

```sqf
this addAction ["",
{
    _this select 1 action
    [
        ["EngineOn", "EngineOff"] select isEngineOn (_this select 0),
        _this select 0
    ];
}, "", -10, false, true, "User1", "_this == driver _target"];
```

If you're a client (not server) and check remote vehicle that is far away from the camera, you'll get an outdated engine state until the vehicle and client camera position are close to each other. Distance seems to be around 6km and doesn't depend on video settings.
