Overall, cultural expectations are everything here so it's best to just "when in Rome, do as Romans do".
There is nothing to be done against old people using noise so I just prepare to stop.
Still agree on the second statement.
That sounds delightful. We should have more bells lightly chimed around us.
The same people tend to ignore the bell. They're in their own world. I usually shout at them to move in that case. A friend of mine instead bought a loud horn connected to a can of compressed gas, which commands attention much more easily than a puny little bell. Works on car drivers, too.
Now if there's not enough room to pass safely and silently I completely slow to the pedestrians speed and THEN calmly say excuse me. But I'm convinced that there is just no universally correct way to do it. If you pass people in any way whatsoever, sooner or later someone is going to get mad about it.
Anyone who is mad that you politely passed them at a safe speed is just too sensitive about these things. You're totally fine there. But "room to pass safely and silently" could still piss people off depending on your speed and distance.
Back peddling or coasting gets people’s attention. Though moving slowly uphill and needing to back peddle is a bit of a test.
Greetings from Sweden, where some people will verbally announce "honk honk" (tuut tuut) while avoiding eye contact – then bump into your leg with their grocery cart.
Well, at least here in Europe I’d have to spend a decent amount of time deciding which language to use.
