Actually, if they would just put filters in places where they are easy to access all these weird tools wouldn't be necessary. Some of them are not only difficult to access, but drip oil in places while changing where you can't clean it up. I am sure in vehicle design that the filter location is quite often an afterthought that is deemed not worth changing once they realized they screwed up.
I had a VW Scirocco one time where original owner installed a kit for a remote oil filter with easy access. That was nice.
