URI like controller/var/controller/var ?

I think even more intuitive would be /cars/honda/civic
You could even do /cars/honda/civic/2012 to include the model year

If you only want one controller, instead of having to have a "cars" controller, you'd just

Code:

$route['cars/(:any)/(:any)'] = 'brand/view/$1/$2';
$route['cars/(:any)'] = 'brand/view/$1/';
$route['cars'] = 'brand/view';

And the brand controller would look something like

Code:

class Brand extends CI_Controller {

  public function view($make = '', $model = '')
  {
    if ( ! empty($make))
    {
       //They entered a car Make
    }
    if ( ! empty($model))
    {
       //They entered a car Model
    }
  }
}

This would allow for urls like:
/cars (list all car makes)
/cars/honda (list all hondas)
/cars/honda/civic (list all honda civics)

There are many ways to do this, but hopefully this gives you an idea.
