When using lodash `each` you can dismiss the `_.bind`:

```js
_.each(routeDetails.legs, function(leg, i) {
  _.each(leg.steps, function(step, k) {
    _.each(step.path, function(point, l) {
      if (l !== 0 || (i === 0 && k === 0 && l === 0)) {
        this.route.path.push(point)
      }
    }, this);
  }, this);
}, this);
```

Also it is better to use only one `each` in a project, either lodash or jQuery as they switch index and value in the callback function.
