No-Fork project, bicycle geometry hacked

I have only been to a velodrome once in my life, and ive never riden on one. That describes pretty much how much acquaintance I have with track cycling (and maby also an indication to the friction between me and tester...iduno). BUT, yesterday i suddenly thought why not go visit the velodrome in A'dam this weekend, and I just might do that. BECAUSE Ed's remark yesterday did spark something regarding these two quotes..

I'm sure any reasonably competent cyclist could ride around any of these problems, since they will all be of small enough magnitude to be lost in the noise, but they are also the kinds of small issue which make the difference between a bike which feels good and one which is annoying.

or a track cyclist travels down the straight at the velodrome

Seriously, Im looking for some serious conversation/discussion here. Let me try and put up a small tree here.
I just checked the wikipadia of velodrome and it says the straights are at an angle of 15 degree. And I assume that riders are able to ride down the straight handsfree? Please correct me if im wrong, im just making some assumptions. So what tester is saying is that he, and many others, are perfectly able to ride a bike with wheels at an angle of, say 15 degrees to normal, handsfree.

Riding down the straight of a velodrome, I guess the bike tends to steer itself up the banking? So if you want to ride handsfree, you would have to counter that with your body?
