I had a hidden button on a car once that you had to push AND turn the ignition key before it would start.
But I am not personally doing this mod so I can't say really why they want to do it, but its probably like you said, for show.
I mean you could get rid of the ignition switch all together (use a few toggle switches for the accessories, and a push button for start like a race car, in a way.), and have your steering wheel permanently unlocked, but I kind of like that my steering wheel locks.
but if I was personally going to do this mod, I would do it how I just mentioned. but that is me, and I am not recommending anything lol.
