Guns are still not hearing-safe outside. And if you're indoors, you probably should double up on the hearing protection (foam plugs with over the ear protection on top)
This one is not that surprising in mass media - there's no way the good guys and bad guys are going to take a pause and actually put on PPE before the shoot out.
Announcing "on your left" is a great way for someone to move left, because more often than not, they're oblivious on the shared paths, and the spotlight effect messes with their head.
We are required to have a bell in Ontario. Ontario, at the minimum, asks us to ring a bell, or verbally communicate, when we are passing people.
I've lost count of the amount of people walking abreast taking both sides of a shared path.
I've lost count of the amount of times I've rang a bell in vain to inform them of intent to pass.
I've lost count of the amount of times I've tried verbally communicate in vain, to inform of intent to pass.
And then these path users, completely oblivious of what's going on, act like I'm the villain when I do pass them despite doing what is required of me. Some even had holler back saying that I should have ran a bell, or tell them.
If one's using a shared path, don't use headphones that completely block outside sound. If one wants to meditate, then get off the shared path.
It is absolutely a people problem just as much as it's an infrastructure problem.
We call them multi-use path (MUP) here. It has a yellow line painted straight down the middle, and people, whether they're walking, running, riding a bike, rollerblading, are expected to stick to their side of the path.
I've lost count on the amount of people on the MUPs wearing something that removes their situational awareness, be it ANC earbuds, or over the ear headphones, etc...
So why did I bring up the lane division? Because on top of people choosing to completely occlude themselves from their surroundings, a subset of them also like to walk/run/etc... abreast, completely taking up the path on both sides. So if you come up behind them, and they're taking up the whole path, you can't get around them without ringing a bell, or asking them. And if they're very engrossed in their conversation, or they're wearing headphones, it's even harder...
The point of a MUP is to share the path. It doesn't give a right for any kind of users to practically occupy the path, and then act very offended when you finally got their attention to get around them.
It has got to the point that I rather bike down the MUPs in the rain, because these users with no etiquette aren't dedicated enough to be out there in the rain.
Rusty rotors has reduced effectiveness. EV with regen uses the actual brakes because the driver hits the brakes hard enough, presumably emergency braking.
The fact that they rust and it's not programmed to regularly enable physical brakes to scrape the rotors could be the difference between the driver can emergency stop in time or hitting something.
There's a reason why TUV flags rusty rotors as a problem.
