This validation rule is to validate when you add some car type, not user.

For this, you need put validation in User model from car_type_id field:

class User extends AppModel {
    var $name = 'User';

    var $validate = array(
        'car_type_id' => array(
            'rule' => 'notEmpty',
            'message' => 'Please, select car type.'
        )
    );
}

And your form:

$this->Form->input('car_type_id', array('options' => $car_type, 'empty' => '- select -'));

Your Controller can be simply:

$this->set('car_type', $this->User->Car_type->find('all'));

However, do not know if this is your entire code to confirm the relationship between these two models are correct.
