That is an issue on bike paths that are build inside a sidewalk, the cycling path is usually build using a smoother surface than the one designed for pedestrians. Plus it sometimes has a brighter paint. I am pretty sure most people don't realize it but they are inconciously attracted to it. It just feels better walking on it.

No, every bike path in a city inevitably has crossings or is laid out next to a sidewalk. People just do their random-walk thing (Brownian motion, really, sometimes) and wander into the bike path.

The ultimate cyclist killer: those stupid extending dog leashes.

Back when I roller skated, the ultimate question: you see a person and a dog, several meters apart. Is there a leash between them? :-)

Double-sided USB-C connections require a handshake before sending voltage. USB-A ports can have the 5v line active at all times. Cheap USB C gadgets often don't make the handshake, they just use it as a 5V input, necessitating an A to C cable.

Interesting. Does UsBC spec/licensing require any sort of notation for products that don’t implement handshake?

There is no handshake, all that's needed are two 5.1 kΩ pulldown resistors. By omitting them the manufacturer saved all of about 0.1c and made their device incompatible with compliant usb-c chargers.

Its pretty safe to assume on a trail if you hear a bell that a bike is coming up behind you.

Or from the side or oncoming and he's just behind the crowd of pedestrians ahead of you.

Yes haha - a bike coming from _somewhere_

Shouting that while traveling too fast is indeed incorrect, but a polite "on your left" or bell while traveling an appropriate speed is considered good behavior to avoid surprising pedestrians.

also - even though the pedestrian has the obligation to move over - a friendly thanks! or thank you! helps all cyclists in the long-run.

This again depends on the jurisdiction and kind of path you're on. Where I grew up, if it's not separated into bicyclist & pedestrian lanes, bikes yield to pedestrians.

On US forest trails, the general rule is bikes yield to pedestrians and everyone yields to horses.

(Obviously pedestrians walking in bicycle lanes are doing it wrong.)

My horn is my larynx. I usually belt out “please don’t kill me” in a stern voice-of-command at my “max volume.” A loud voice travels very well through car windows at short distances, even for big soundproof vehicles.

I assumed this bell was for alerting pedestrians or other cyclists wearing noise cancelling headphones.

That’s a crappy pressure vessel holding 350ml of 80psi air, for about 100J of stored energy. I’m not entirely sure I’d be comfortable with that, especially anywhere with my face in the line of fire it it fails.

Your bike already has two crappy 80psi pressure vessels, why not three?

Those two pressure vessels are highly engineered and are wrapped with materials with pretty good tensile strength. Also, they’re made out of materials (fabric and rubber) that absorb a decent amount of energy when they tear and that don’t fragment. And the whole assembly usually depressurizes slowly.

Having personally blown up beverage bottles by overpressurizing them (be very very careful doing this!), when they go, they go violently.

Overall this bell seems like the wrong solution, and it took me a while to realize not every country has outlawed headphone wearing for bicyclists, something I guess I took for granted.

It doesn't make sense for a car driven to use headphones, so not sure why it'd make sense for other vehicle-users to use them either, as you say, we really do use our ears to help navigate traffic so allowing people to be so careless seems... Careless?

Political cyclists hate this because they think anybody who complains is just a car driver concern trolling, but having been hit by a cyclist I can attest to it being a real problem. Sure I wasn't in real risk of dying, but I was bruised and scraped up for a week after that. I've done my fair share of road cycling in my years, I don't do it now but I still cycle on trails. The way some cyclists push back on any criti…

Did you consider that your talking about GROUPS of people where _some_ individuals from ALL groups regularly behave poorly and deserve criticism and action? Or is that too much of a nuance against tribal thinking?

Why do you think I'm not aware of this? Did I not just explain how different people who do the activity have different perspectives, priorities and proclivities? Did I not just explain how I disagree with the way some cyclists conduct themselves, while plainly being aware that not all cyclists are like this?

Maybe none of this way apparent to you, despite it being plainly written out in simple English, because... I don't know actually. Can you explain your failure to read?
