Yes, I argued the same thing about a year ago - and lost the change in my
pocket :)
Since then, I have not forgotten this.

This is also correct. I remember one time arguing this specific point
with someone. I put a static route for 187.192.1.0/24 to show this:
R2#show ip ro 187.192.1.0
Routing entry for 187.192.1.0/24
Known via "static", distance 1, metric 0 (connected)
Routing Descriptor Blocks:
* directly connected, via Serial0
Route metric is 0, traffic share count is 1

You've made an assumption that all routes that show up as connected have
an AD of 0. I believe this is a false assumption.
When you add in the route - and it shows up as "connected" please
provide a "sh ip route x.x.x.x". I suspect the AD will be 1 and it will
be "connected".
