Some cyclists do over react, and some of those have helmet cameras.
This guy:

Seems to over react over a lot of things. Watch his latest one about red light and planning. yeah, bad driving, but he sounds like he is going to cry. It wasn't that big a deal, certainly not worth the argo. Maybe stopping and clapping or something patronising if you really must.
On the other hand, this guy does have some very, very good videos (depending on how you look at it). One where he gets hit by a wing mirror and nearly ends up under a car. I couldn't fault
any reaction to that. Especially as the driver didn't stop.
I'll be honest, if you look at some of my past videos I probably over react, or at least post really boring stuff. I seem a lot more laid back recently, but if something is bad I will react. I do try to remain calmer and let things go though.
