           | I'm guessing some law (law-abiding) gives you the right to
           | bother people who are using their own feet instead of wheels
           | because you want to pass them and they should have to

           | 
           | In my experience (in my locale) as a cyclist you either give
           | pedestrians a wide enough berth, dismount so that you can
           | pass them if it is crowded and there is no passage, or use
           | the vehicular road.
           | 
           | I remember violating this one time when I belled someone that
           | I wanted to pass on the sidewalk. But I was a child at the
           | time. Even more self-centered than I am now.
           | 
           | These seeming rules for yielding to cyclists are worse than
           | the laws and norms when cars interact with bicycles, by the
           | way. At least where I am: cars never honk cyclists. They have
           | to wait for them or find a window to pass them safely. They
           | can't honk them into the ditch or something.

             | No. There are just people who will walk on a designated
             | bicycle lane because they haven't seen the signage, are
             | ignorant or careless about it, or will just cross it to get
             | somewhere else. All while wearing ANC headphones. This
             | isn't about bothering someone, but warning them. It's
             | really no different from someone jaywalking without seeing
             | you, and honking to make them aware of that. Or are you
             | supposing you'd just break and wait until they're finished

         | 
         | Quite. It drives me up the wall when cyclists not only use the

         | I use regular headphones (not over-ear and not really noise

               | that my opinion is that other rights' organizations
               | SHOULD be against it). Quoted directly from tbe website
               | of the, quite well-regarded and not off their rocker,
               | Fietsersbond [1] (under the header "Veilig gevoel?",
               | translated by kagi):                   The Fietsersbond
               | (Cyclists' Union) isn't against wearing a bike helmet. If
               | you feel confident, you cycle more safely. It can be wise
               | to wear a helmet in high-risk situations, for example,
               | for seniors on e-bikes. Unfortunately, it has been proven
               | multiple times that forcing people to wear a helmet
               | actually backfires. People start cycling less.         A
               | helmet mandate makes cycling feel more like a dangerous
               | activity--something you should be afraid of. Getting
               | around by bike also becomes more complicated. After all,
               | what do you do with that helmet when you're not wearing
               | it? And what happens if you forget the helmet or if it
               | gets stolen? These are all factors--whether justified or
               | not--that make choosing a bike less convenient.
               | 
               | So yes, given that you got into an accident, it is very
               | obviously better if you had worn a helmet (and knee,
               | elbow and wrist pads). However, we don't want only to
               | reduce mortality rates on accidents, we actually want to
               | reduce the amount of accidents wholesale. The above point
               | (and the point in my previous post) is that given
               | mandatory or officially encouraged helmet wearing, you
               | are more likely to get into an accident in the first
               | place, further reducing the number of people willing to
               | cycle, and thus safety for all those who still are
               | willing.

               | I wanted to react to your car/seatbelt point, but I

           | 
           | Here in the UK, there was an infamous case of Charlie
           | Alliston who ended up getting a ridiculous 18 months prison
           | sentence after colliding with a pedestrian who hit her head
           | and subsequently died. He was riding a "fixie" without a
           | front brake and was cycling at around 18mph through some
           | green traffic lights. The pedestrian was crossing the road
           | further on (i.e. not at a junction which is fairly normal)
           | and wasn't paying enough attention, so Charlie shouted at her
           | to get out of his way. He started to reduce speed (rear brake
           | only), but then decided that he could just aim for the gap
           | behind her, but she then reacted to his shouting by stepping
           | backwards into his path.
           | 
           | The point is that the judge awarded such a tough sentence
           | partly due to Charlie not taking all available actions to
           | avoid a collision and also because his bike was illegal to
           | use on the road due to having just one brake. So, if you rely
           | on a bell to clear your path, you could be held liable if
           | they don't respond and you collide.

             |

       | Seems to be some misunderstanding of what bike bells are for
       | here...
       | 
       | A bell is helpful in a situation where a pedestrian is not aware
       | of an approaching bike. The bell informs the pedestrian of two
       | things:
       | 
       | 1. That there is an approaching bike.
       | 
       | 2. Roughly were the bike is approaching from.
       | 
       | The hope is that the pedestrian will then behave in a predictable
       | way to allow a safe pass by the bike. In almost all cases the
       | pedestrian will be able to simply continue doing what they were
       | doing before they heard the bell.
       | 
       | If a pedestrian can not hear bike bells, for whatever reason,
       | that is not a problem. They can just stay consistent with the
       | centreline of the path/road/way. They then have a responsibility
       | to shoulder check when shifting from side to side.
