I really hate getting honked at by the car behind me because I'm not turning right when there's a no turn on red sign.

Dude they turn left across the max tracks on Yamhill downtown by Nordstrom all the time even though there are big no left turn signs.

And what is the aversion to turn signals in this city? I ride a bike and religiously use hand signals.

Yeah, getting rid of turn on red kinda requires adding light up no turn signs (like what you might see at a rail crossing).
