Laravel form does not assign corresponding values to the fields of a form

im in deep trouble. im using ajax to submit a form in laravel. when i submit a form it does not submit correctly because each field of laravel does not have its assigned value. first field of laravel form is _token field, when i inspect my submitted data through chrome it shows _token field is empty and request assign my _token field to the very next field of form. in the same way each field dont have its corresponding value. i attached snapshot of chrome inspection please look into it. here is my code for a form.

<form id="add_car_2" class="s-submit clearfix" method="POST">
                                
                                <div class="row">
                                    <div class="col-md-6 col-xs-12">
                                        <div class="b-submit__main-element wow zoomInUp" data-wow-delay="0.3s">
                                            <input type="checkbox" name="security_system" id="security_system" />
                                            <label class="s-submitCheckLabel" for="security_system"><span class="fa fa-check"></span></label>
                                            <label class="s-submitCheck" for="security_system">Security System</label>
                                        </div>
                                        <div class="b-submit__main-element wow zoomInUp" data-wow-delay="0.3s">
                                            <input type="checkbox" name="air_bag" id="air_bag" />
                                            <label class="s-submitCheckLabel" for="air_bag"><span class="fa fa-check"></span></label>
                                                <label class="s-submitCheck" for="air_bag">Air Bag</label>
                                            </div>
                               </div>

    </form>

here is my ajax function to submit this form.

$("#add_car_2").submit(function(event) {
    event.preventDefault();
    var url=/cars/ + $('#car_id').data('carid');
    $.ajax({
        url: url,
        type: 'POST',            
        data: new FormData(this),
        processData: false,
        success: function (data, status){
           console.log(data);
           console.log(status);    
        }

    });    
});

when i submit this form through ajax it shows failed to submit because each field of form does not have its correct value
