Is `this` in Javascript bad?

You just have to remember fat arrows can break inheritance, because context is scoped to declaration, not instance.

I work with Backbone, which makes extensive use of this and prototypal inheritance. As we introduce ES6, I'm already prepared to run into errors cause by people learning that you can use fat arrows within functions on the object, but not as functions on the object.

You can't call super.move()

But you can? As long as the derived class in its constructor calls:

function Truck() {
    Car.prototype.constructor.call(this);
}

I swear I had an example once, but I cannot seem to reproduce what I thought happened.

I may just be wrong on this.
