Knight street bridge as separated paths on both sides of the bridge, there is no reason why anyone has to ride against the flow of traffic on either side - you don't even have to cross the road to get to the other side to be going with traffic, you just go under the bridge and up to the other side…slightly inconvenient, maybe - less convenient than causing a scene because somebody (me) didn't feel like giving you the right of way while going against traffic, not really. Know what I am saying?
If everyone is going the same way, nobody has to stop - and as far as I know, the whole uphill vs downhill yield thing is a trail thing, not an everyday out on the roads kind of thing. You don't expect people to yield to you when you drive uphill the wrong way on a one way street in a car do you? lol

Seems to me that it's bidirectional. So yeah, you're being a dick about it.
