Can’t insert data on my database from laravel

When I try to insert data into my database, Laravel does not insert the records, but it is strange because when I migrate the tables to be able to perform the database, Laravel creates them without any problem, I do not know what I can be doing wrong if the migration run but stored no

Route:

Route::post('/proyecto', [ctrlCars::class,'store'])->name('cars'); 

Controler:

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppModelscars;

class ctrlCars extends Controller

{
    public function store(Request $request){

    $request->validate([
        'carRegistration'=> ['required','min:6'],
        'name'=> ['required','min:6'],
        'fromProduction' => ['required','min:6'],
        'stateStored'=> ['required'],
        'model'=> ['required','min:4'],
        'dateAssembled' => ['required'],
    ]);

    $car = new cars;
    $car->carRegistration = $request->carRegistration;
    $car->name = $request->name;
    $car->fromProduction = $request->fromProduction;
    $car->stateStored = $request->stateStored;
    $car->model = $request->model;
    $car->dateAssembled = $request->dateAssembled;
    $car-> save();

    return redirect()->route('cars')->with('success','Registro guardado satisfactoriamente');
}}

Answer

The problem is from your template. The select tag should have a name attribute. Change your template to this

   $car->dateAssembled = $request->dateAssembled;
    $car-> save();

    return redirect()->route('cars')->with('success','Registro guardado satisfactoriamente');
}}
Template:

@extends('header')

@section('content')

<div class="container w-10 mt-5 border p-4">

    <form action="{{ route('cars') }}" method="POST">
        @csrf

        @if (session('success'))
            <h6 class="alert alert-success">{{ session('success') }}</h6>
        @endif

        @error('carRegistration')
            <h6 class="alert alert-danger">{{  $message }}</h6>
        @enderror

        <p class="h2">Registro vehiculos</p>
        <br>
        <div class="row">
