You're right, but it's still true that the headtube angle introduces nonlinearity to the steering response. It also allows you to lean while steering, something that is hard to do with a vertical HT. Just using the word "nonlinear" helped make things clear.

Perhaps, but it's not wrong, and I had no trouble understanding it.

Agreed, it was a little confusing to introduce this analogy. The explanation would be fine without it.

I think he is referring to steering stability at speed but I'm confused as well. Clearly even he was a little confused by his own reasoning. Care to 'splain it?
