a healthy, quick, and fun way to commute, while appreciating the beauty of the fallen leaves and colour surrounding nature that autumn is.

Commuting by bicycle is so nice! You exercise and you are outdoors!
Even though the rain in fall can be a bit annoying. And the leaves can make the roads slippery too.

because cyclists do not have priority on the streets, and are seen as more of an annoyance for motorists, and road rage in the UK is real.

I'm so happy that we as cyclists have separate cycling lanes almost everywhere here in The Netherlands. Cyclists almost always get priority over motorized traffic. Even the traffic lights jump to green faster for bicycles in some spots.
It's very good that you are making yourself visible with your outfit, the bicycle lights and the reflectors. The mirrors are also a good addition!
And I think a helmet is never a bad investment; you only have one brain, so you'd better be careful with it.

You really have a nice red bicycle!

Happy cycling!
