I’m sorry the bicyclist ended getting shot for his idiocy, but bicyclists not obeying stop and other traffic signs is common where I live. I’m willing to bet a lot of money that the great majority of cyclists sail through stop signs (and many time traffic lights) without stopping. So while cyclists have rights, they also have responsibilities.
I commute by bike and yes I blow stop signs and traffic lights. If there is a car in the intersection I will stop for 4 ways. I always proceed with caution.
On the other hand. People who are in cars who pass me with inches to spare are upsetting. Most people are bad at judging distance and speed.
I ride like I am invisible and just expect drivers to not see me.
I obeyed traffic laws in general when I was a full-time bicyclist, because I knew how vulnerable I was to either hostile or inattentive drivers.
The only law I would’t completely obey was the stop sign. I wouldn’t absolutely stop, but I would slow down and ascertain my safety. I was never careless or chancy when it came to my road safety.
I live in a rural area with narrow, hilly, twisting roads, yet almost every weekend, I come around a curve at the recommended speed limit just to be confronted with a huge group of pumping butt-cheeks doing 10 mph.
I can understand why cyclists do what they do.....but they need to make sure the area is adequate for it and have their vehicles 'taxed' since they want to share the road.
Just my 2 cents.
