Being a cyclist most of my life until I had kids (only been driving for about 5 years) I have to say most cyclists are good (having to share Karori road with a lot of them) but what pisses me off are the go-pro righteous warriors who love to post videos of bad drivers but never show footage of themselves skipping lights, using the centre line as a cycle lane or dodging through slow moving traffic as if the road rules don't apply to them.
This applies to motorcyclists as well.
My wife being in the passenger side is the one who usually gets a close up view, and thinks most cyclist don't show enough caution. " "It was the cars fault" or "But I was in the right!" doesn't make for fitting epitaph" is something along the lines of what she says.
If you choose to share the road with cars while on a lightweight frame of metal or carbon fibre then expect to come off the worse when either you or the motorist makes the mistake.
Its like gambling with your life and being on a bike drastically reduces the odds on you winning. I've ridden bikes for over 30 years but I wouldn't get on a bike on Wellington roads if you paid me.
