won’t help for clearing your head, but try hooking up with Critical Mass (you’ll at least get one day when it’s safe-ish to be on the roads)

Probably not the answer you want, but if other road users are being dangerous around you then it would be ideal to try and look out for yourself more, if at all possible.

At intersections make sure drivers can see you, when in traffic try and stay visible in their mirrors, avoid blind spots whenever you can, and try to "read" what others are doing with their car - as some won't indicate to show their intentions. Speed is an important one too - if a driver was to righthook/cut you at an intersection, can you evade it or stop in time?

Try and adapt your riding style to a way that allows you to maintain visibility of yourself, and the environment around you on the road - drivers are protected in a metal box, but we aren't

Edit:

The real fix for these issues is separated bike infrastructure IMO, as well as better education for drivers about people on bikes

Get an Airzound bike horn and a helmet mounted 360 GoPro if you have the funds.

The streets are a battlefield unfortunately, that much holds true in even some of the better parts of the world for cycling.

Gotta stay defensive out there, and push your local government hard for protected infrastructure. A large part of my commute is safe due to there being fully separated infrastructure.

I've found that drivers are a lot more courteous when I'm riding my cargo bike and have my kids on the back.

According to Norwegian US news coverage, the bike has nothing to do with this, it’s how NY works
