Have you even been in a bus garage? It's basically yellow lines painted everywhere, and associated safety rules around them. They let staff know where buses are supposed to drive, where they are stored, where the pits and hoists are, and so on. If staff ignore the rules, the staff are disciplined. If management tells the staff to ignore the rules, management is disciplined. Heavy machinery has to be dealt with respect, both sides can break the rules, and neither side is presumed to be of blame. Well, at least ideally. If all of that was tossed aside, we would be back to the factory days of a century ago. Lives were lost simply because certain lives were disposable, at least in the eyes of many factory owners. Incidentally, the disposable lives were not those of the factory owners.

Like I said, I understand why you have a dashcam. It can be a valuable tool to prove your innocence should the need arise. The thing I take issue with is the presumed guilt of cyclists. Yes, there are times when cyclists are to blame. On the other hand, there are times when motorists are to blame. Those circumstances are common since most cyclists realize that they are the ones who are going to die. A lot of motorists don't seem to have the realization that they are the ones who can take lives. At least in the moment.

Here are some things that I have encountered as a cyclist:

- I have been in a hit-and-run. The impact was hard enough that I chunk of their car was broken off in the accident and loud enough that people could hear the crash in their houses. Witnesses said there was no way the driver could have not noticed they hit someone, yet they left me for dead. That is not how you treat another human being. I don't know who is to blame here since visibility may have been an issue, though I was following traffic laws to the letter, but the police said the driver's behaviour after the fact was likely the product of drunk driving.

- I have been intentionally hit by a driver. At least that is the only way I can explain it since they were stopped behind me at a red light and decided to go straight through me while I was waiting for an opening to make a left turn. Yes, I was signalling. Again, a hit and run. The police did not want to deal with it.

- The right hook is famous amongst cyclists. Believe it or not, these aren't always the result of cyclists passing to the right. I never pass to the right since I realize that many motorists don't signal turns. (I cannot predict what they will do, so I don't know when it is safe to pass.) Then there is the visibility factor that you mentioned. Yet vehicles will pass me and turn across me on a regular basis. I have even had that happen when the vehicle is in another lane.

- I have had vehicles make left turns from behind me because they are impatient and had poor judgment on the speed of oncoming traffic. I have seen several near collisions between two automobiles because of that, and it places me as a cyclist at greater risk.

- Certain groups of people like to distract cyclists. I'm not talking about people honking or screaming expletives here. I'm talking about people screaming absolutely nonsensical things at me in an attempt to pull my attention from the road.

I'm not bringing up these examples to say that motorists are always to blame. I know they aren't. I've certainly had my sloppy days on the road, though, ironically, those seem to be the times when I had the fewest issues. I'm bringing it up because there are plenty of times when large bundles of kinetic energy aren't following the law and are endangering people's lives. I'm not saying this is because your veering cyclist should avoid the blame. Most of the cyclists I know would frown upon such behaviour even if there wasn't an accident. I'm saying it because there are all too many cases where motorists seem to believe they are never to blame, even when they are not paying attention to the rules of the road themselves, or they make a bad judgment call, or even when they are acting in malice. It's like that because they have no skin to loose in the game (or, at least, not as much).
