Committed drivers honks at cyclist

This pickup making a right turn didn't see me until it already committed to making the turn. He tried to stop, but then kept on and just honked. My questions is...why honk? I felt like they were trying to say, "I'm going! Don't hit me!" The funny thing is I have limited braking power when it's raining like this. Honking doesn't make me brake any better. Perhaps they were just trying to acknowledge my presence. If so, it worked. I couldn't stop if the truck stopped too, so I did feel better knowing the driver at least saw me.

Yes the white truck ran a stop sign but something to consider is how about putting on your flashing lights to be seen

Whilst flashing lights are more attention grabbing, the cyclist here had really good solid lights easily visible had the driver looked.

I agree, it's so important to make yourself as visible as possible while riding a bike! I ride with 72 LED's. Details on my setup here: www.sheridestoday.com/blog/2019/10/17/fantasticlights

Also, the driver didn't run a stop sign. Driver turned onto a road with street-side parking. Visibility is poor. I have to inch onto the road when I'm driving just like they did. The driver did fine, once they committed to going, I'm glad they kept going. If the driver saw me so late and then STOPPED, I would have crashed.
