Using Request for Laravel Route::get() controller functions

Using Request for Laravel Route::get() controller functions

// Here's what my web.php file looks like with a locale prefix on all routes for a multilingual app. 
// To manage the locale, I'm using two middlewares:
// the 'locale.default' middleware to set a default locale, 
// and the 'locale' middleware to call app()->setLocale($segment) on the first request segment. 
// The two middlewares appear to be working fine.

Route::prefix('{locale?}')->middleware(['locale.default', 'locale'])->group(function() {
      Route::get('/car/{id}', [
            'uses' => 'CarController@getCar',
            'as' => 'car',
            'middleware' => 'auth'
        ])->where(['id' => '[0-9]+']);
});

// Problem: In CarController's getCar($id) function, the $id parameter has the locale (en, fr, it) instead of 
// the actual id of the car being passed.

public function getCar($id)
{
   $car = Car::where('id', $id)->firstOrFail();
}

// I could do the following but it adds the extra unnecessary passing of a $locale parameter everywhere, so I'll avoid this.

public function getCar($locale, $id)
{
   $car = Car::where('id', $id)->firstOrFail();
}

// If I change getCar()'s parameter from $id to $request of type Request, I can successfully do the following.

public function getCar(Request $request)
{ 
   $car = Car::where('id', $request->id)->firstOrFail();
}

// Is this a good solution?
