In your case, AJAX can be used. But IMHO, as well as generally accepted development principles, it is advised to first register the user, and then his car.
Well, if all the same perversion is your chip
Leave one route and shove everything into one method
Route::post('reg', '[email protected]);

class regController extends Controller
{
    public function regClient(Request $request){

      DB::table('client')->insert([
          ['fio' => $request->get("fio"),
          'phone' => $request->get("phone"),
          'gender' => $request->get("gender"),
          'address' => $request->get("address")
          ]
      ]);
      DB::table('avto')->insert([
          ['Marka' => $request->get("Marka"),
          'Model' => $request->get("Model"),
          'Color' => $request->get("Color"),
          'Number' => $request->get("Number"),
          'Status' => $request->get("Status")
          ]
      ]);
      return  'Ок';
    }
}
