Laravel - How to check if One To One relationship exists?

Let's say I have 2 models: Car, Driver.

Car model:

<?php

class Car extends \Eloquent {
    public function driver()
    {
        return $this->belongsTo('Driver');
    }
}

Driver model:

<?php

class Driver extends \Eloquent {
    public function car()
    {
        return $this->hasOne('Car');
    }
}

How to query one or all cars that don't belong to any driver yet? How to check whether queried car belongs to any driver?

Eloquent way:

$driverlessCars = Car::has('driver', '=', 0)->get();
// Collection of Car models
