The point of that demonstration is that people do things without consciously thinking about them. You don’t have a choice, I am controlling your behavior in an extremely minor way.
But I do have a choice, simply because your ego wants to believe otherwise does not make it true. I find people who do that annoying and will refuse to change course or speed unless I am feeling ornery in which I will abruptly stop or slow down "controlling" their behavior to dodge. Only I don't see it as controlling their behavior because they could just as easily choose to run into me and I have no control over which option they chose.
