The point I tried to make (unsuccessfully in your case obviously) was that I started low cost & simple so my mistakes were manageable. I have never had any lessons or quals (apart from Sea Scouts "Anchor Badge") but I have made an effort to teach myself.
I wouldn't dare spend £K100's (even if I had them) & just try to drive it.
Not sure what is "self-righteous" about that, but I accept that it is your perception, even if I can't understand it. And you? I notice you haven't actually ventured any opinion of your own other than attacking my post.
