[flagged]

this was not really an issue before food delivery apps came into fashion

btw. kids up until certain age can pretty much in all countries ride bike legally on sidewalk, are there any countries where 8yo can't ride bike on sidewalk?

Draw a line, say this is for bicycles, pedestrians and cars have no business here, and bikes have no business being on any other lane as long as these exist. When bikes have to go through areas where people walk freely, they need to limit their speed to a walking pace. People should not wear headphones (noise-cancelling or not) when going through traffic as pedestrians. Take them off when crossing! People should not…

Unfortunately, the UK seems almost incapable of building usable cycle infrastructure (possibly excepting London). Your idea is just a recipe for magic protective paint and even more abuse of cyclists who don't want to be forced to use ridiculously badly designed infrastructure. e.g. Here in Bristol, we have an infamous shared cycle/pedestrian pavement along Coronation Rd that has a few trees completely blocking the c…

Sorry I didn't write "don't have trees in the middle of the cycling lanes", I should have been more clear.

Also "don't let the restaurants cover the pavement with tables" follows the same logic.

Perhaps, planners should travel the route three times for every permitted mode of transportation, including walking, biking, and driving.

Nope, but now the worldwide geopolitical situation is such that it might at least be feasible?

Yes, but again, what's your problem with additionally taking steps to make things safer? Unless you somehow see technologies such as this distracting from creating a safer environment. But this was developed by Skoda, so I doubt that if they hadn't done this, they would have lobbied for more bike lanes instead.

750 Hz. Baby crying sound is around 300-400 Hz and let me tell you my airpods pro definitely let me hear the baby cry. I think Apple built that as an obvious safety feature.

Interestingly, all the shrillness noises (chalkboard, balloon or polystyrene screech) are in similar frequency too.

I think it's time for some sort of a safety standard for a sound frequency to be reserved exclusively for alarm/alert use and that ANC systems have to let through. It goes without saying, use of said frequency should be prohibited for other purposes, especially marketing.

Ha, I had the same idea before I realized it’ll just be used for ads. It would be cool for pilots’ announcements on a flight, or approaching stations on the train etc. But CVS will use it to tell you to download their app and enroll in ExtraCare Rewards. Or “Did you know you may be due for more than fourteen vaccines all at no cost to you?”

A horn or bell is mostly for telling other people "hey I'm here, stay out of my way and dont suddenly cross into my path" My opinion as a cyclist is that I should basically only be using my bell on pedestrians when the pedestrians are wandering onto the bike lane. If im cycling through a shared space, I find it extremely rude to ring the bell, because it feels like I'm telling people to get out of my way, but they ha…

> With cars, I will sometimes proactively ring my bell at them if I think they're not sufficiently aware enough of me though. There's only a few types of car that will be "aware" of cyclists and I don't think ringing a bell will help their algorithms. Getting the attention of a driver, meanwhile, is difficult with a bell as often they'll be in a semi-soundproof cage with loud music on. (Also deaf drivers are a thing)…

> I've never really considered using a bell for motorised traffic.

It works surprisingly well if the car isn't moving quickly. Cars aren't as sound isolating as you'd think. My main use-case is that a car is stopped at an intersection, or crossing my lane so they can turn, and I'm worried they'll pull out and hit me because they're looking the wrong way focused on car traffic, and in these situations they almost always hear my bell.

> If im cycling through a shared space, I find it extremely rude to ring the bell, because it feels like I'm telling people to get out of my way, but they have just as much right to a shared path as I do. It’s certainly rude to ring the bell in a aggressive manner, but many bells are capable of producing much softer, more polite sounds. In super busy old European capitals I find that people increasingly just ride aro…

I still think that ringing bells at people is a little rude, regardless of the tone. Like imagine if you were at the grocery store, blocking the isle and someone lightly chimed a bell at you instead of just saying "excuse me".

IMO if I'm in a dense pedestrian zone and I can't go around people and I can't communicate by voice, it means I'm going too fast.

Do horns and bells really prevent accidents? In order for e.g. a horn to work you need enough time that the driver processes the situation and decides the horn will communicate something AND enough time for the pedestrian or whatever to process that and react to it. Generally it's a lot easier just to press the brake, and more importantly be travelling at a speed and in a manner where the brake is sufficient. Structu…

I've been a cyclist in SF and in Amsterdam, both for many years.

In SF I used my bell much more aggressively. It was mainly for cars, if I'm in or entering their blind spot and my spidey sense tells me they are considering an action that places me in danger. For example, we all know when driving when the car in front of us is thinking about merging, even before they indicate (often I feel like I know before they do). I also used it for pedestrians stepping out into the street who are maybe looking past me for oncoming cars but somehow don't see me, or when approaching 'blind' situations like a sharp corner, a driver pulling out of a driveway but there is a tree between us, delivery drivers stepping out from their truck, etc. I can't say how many accidents have been prevented (the person may have eventually looked and seen me), but I can say that my bell has triggered people to look and see me earlier than they were going to had I not rang it.

In Amsterdam my bell is used much more sparingly. It's mostly for tourists stepping into (or considering stepping into) the bike lane. If they are already in the bike lane, I almost always prefer just to slow down a bit and dodge them, as ringing the bell often triggers a deer-caught-in-headlight moment or erratic behavior, which increases the chance of an accident or that I have to come to a full stop. The other situation is to express dissatisfaction at cars blocking bike lanes, cars/bikes not yielding, drivers blocking intersections, or other dangerous behavior. This isn't preventing an accident but I'd argue it is still important, as social control affects how often we make bad decisions. Outside the city I also use my bell to let other cyclists know I'm passing.

So yeah, I'd say bells prevent accidents, but obviously not as well as good biking infrastructure, where pedestrians, bikes, and cars have clear separate spaces, and visibility of cyclists to drivers is high.

Wearing a seatbelt cost next to nothing in inconvenience. Not being able to listen to music or have phone calls with noise cancellation while walking does not really compare. Of course this requires compensating for the loss in awareness through hearing by looking more diligently before crossing a bike lane, but unfortunately, some people never learn this, or only through a few close calls. "Annoyingly" ringing a bel…

"Next to nothing in inconvenience" is the perception now . It certainly wasn't the perception when seatbelts were introduced. The ability to listen to personal music while walking is less than 50 years old: before that, you had the radio or nothing. Even that would not be an intolerable inconvenience for most. But I was more thinking: > People should not hear loud music when driving - max is normal speaking voice lev…

> People should not hear loud music when driving - max is normal speaking voice level.

Oh, completely agreed on that one. In a car, you are also by far better protected than any cyclists you might encounter, so you shouldn't make it harder to hear their signaling. (I still wouldn't rely on any car having heard my bell if I don't get any other confirmation that the driver has noticed me, e.g. sufficiently slowing down as they are approaching the intersection where I have right of way.)

But GGP also said

> People should not wear headphones (noise-cancelling or not) when going through traffic as pedestrians. Take them off when crossing!

and that's what I think goes too far. Why should I remove my headphones if I look both ways before crossing a bike lane or road?

The ideal rule would of course be that only those pedestrians remove their headphones that are otherwise inattentive... Although I have my doubts that they'd remember.

Bicycle bells are mostly for warning pedestrians when approaching from behind and passing on shared-use trails. I ride on shared infrastructure and cannot afford to build new infrastructure when my town will not. Not warning a pedestrian when approaching from behind introduces the possibility of collision if the pedestrian makes a sudden change in his walking course. I typically use this etiquette: Passing a single p…

I wonder if you are German?

Spending some time in Germany from Holland I notice there is a significant difference in cycling etiquette :)

Especially regarding “passing a cyclist” which also touches on the essential difficulty with having only one “ring” sound.

Always when Germans pass me on the bike and they ring I get slightly annoyed because I interpret it as a “get out of the way” ring, and I feel like there is enough space. But perhaps it’s just the cautious “don’t do anything unexpected” ring.

A Dutch person would rarely ring at another cyclist in the former way. But they also might be less safety focused while cycling (see also: helmet usage). Or we have safer infrastructure already.

On a road bike, however, I too ring at pedestrians “preemptively”. For sure GPs remark of “if you need to ring you’re going too fast” applies here but that’s the essence of road cycling.

Ironically I’m also annoyed when road cyclists ring at me for the same reason.

Just shows the case for having 2 clearly different types of rings.

(Also for cars to have a “thank you” horn, haha)
