Dealing with homicidal drivers
In many cities, doing a 35 km (22 mi) commute will take you through parts of the city with different socioeconomic levels and different driver behaviors.

Cyclist behavior that works well in one part of the city can lead to road rage in another place. It's valuable to recognize this and adapt your approach at different parts of your commute.

Some years ago, my commute took me through some quiet streets of a well-to-do suburb of mostly older residents. It took a few interactions, where a driver would look right at me and then apparently try to run me down, for me to realize that they simply didn't see me. They were looking for cars. It's like These are not the 'Droids you're looking for. They are looking for cars, not bikes.

Knowing the area you're riding from, I would describe it (for other readers) as rural / urban interface. There are new developments, and little infrastructure. Roads become congested early, and stay congested late. It's also Winter here now, so it's often only half-light or dark when commuting. Because of the ongoing development there is a higher than usual number of tradesmen (tradies) driving utes (pickups for US readers) and commercial vehicles. Their focus is on getting to their current job. It's not an area where I would choose to ride.

So, either recognize the local conditions and adapt to them in a safe way, or find another route. Another route may not seem practical, but on a 35km commute, a safer route that involves a 3km detour will not be much slower (it may even be quicker), and could save you hospital time in the future. You could maybe drive a short distance to the start of your safer route.

Another change you could make is to use a helmet-mounted light. They shine where you look. So when you look, the drivers are more likely to notice you. Be careful not to get one that's too bright though. If you dazzle the driver then they actually can't see you.
