So, cyclists, what do you have to say? Do you condone the actions of these morons? What would you suggest be done differently?
No, of course not. Why would you think we do?
Then again, it helps to understand that even if you follow every rule of the road, belligerent or inattentive drivers kill cyclers far more often than the other way around.
Utilizing some crazy tactics on the road - like making sure you're pissing people off or jumping onto the sidewalk for some bits - is more survival than not.
Why? Because I could ask the same of drivers that you ask of us. Those jagoffs who purposefully sideswipe cyclists, occupy bike lanes, or are generally not paying attention - do you condone those drivers? No, of course you don't.
The only difference is that seatbelts and airbags ensure people in cars survive most accidents. When your protection relies on other people knowing that you're there and a foam helmet, your habits change.
If I have to take up the entire lane because I don't feel safe, I'm doing it. If I have to use a bull-horn as I pass a long line of traffic so that some idiot further ahead won't pull out in front of me to turn right, I'm doing it. If I have to be obnoxious in any way shape or form so that it means I don't end up in the ER, I'm doing it.
I don't think it creates a very good driver-cyclist dynamic or relationship. I'd much rather have two lanes for cars, and the rest reserved for public transport and cyclists with some concrete inbetween. For old urban areas, I'd much rather have only public transport and bike roads, since IMHO - population density is becoming a serious issue and cars only work efficiently below certain thresholds.
But, really OP, the best way you can understand why some idiot cyclist might do something is to try it yourself. Spend a month cycling around town and see what happens. After biking for a year, the scant few times I do drive I really notice the cyclists who follow the rules of the road and appreciate them.
And yes, I know from experience how dangerous biking can be - even if you're following all the laws. I have a $32,000 hospital bill and two shoulder surgeries on my dominant arm to show how safe following biking laws can be as long as the driver doesn't pay attention.
