Also, it's prudent to consider one of those conditions to be aggressive behavior from a car behind you (horn, etc). They're proudly boasting of their non-understanding of how to fluidly pass non-lane-width traffic, so it's just safer to take the full lane and ensure they'll either change lanes or wait for a lull in oncoming traffic instead of half-passing then cutting into you.
Exactly. One of my accidents was when a taxi driver honked at me, tried to overtake and hit the front of my bike and pulled in my front tire when trying to aggressively merge back into the lane I was in. Completely destroyed the front end of my bike. I was able to jump off the bike away from the vehicle to avoid getting hurt.
