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.

Considering that it's data, you should store the list of valid choices in the model.

var $carType= array('a' => 'Honda', 'b' => 'Toyota', 'c' => 'Ford');

You can get that variable in the Controller simply like this:

$this->set('fieldAbcs', $this->MyModel->carType);

Unfortunately you can't simply use that variable in the rule declaration for the inList rule, since rules are declared as instance variables and those can only be initialized statically (no variables allowed). The best way around that is to set the variable in the Constructor:

var $validate = array(
    'carType' => array(
        'allowedChoice' => array(
            'rule' => array('inList', array()),
            'message' => 'Pls select type.'
        )
    )
);

function __construct($id = false, $table = null, $ds = null) {
    parent::__construct($id, $table, $ds);

    $this->validate['carType']['allowedChoice']['rule'][1] =
    array_keys($this->fieldAbcChoices);
}
