I've been using the PineBud Pros for a while now and have liked them a lot. They've lasted longer than the airpod pros I had beforehand and the noise cancellation isn't perfectly silent or anything but it's definitely good enough for what I want noise cancellation for. They don't have wireless charging out of the box but there is technically a community project that adds it if you have the skill set to take them apart and modify the case/PCB, but that's obviously a lot of work lol. They also sell individual replacement earbuds and the case if one breaks which is a plus. Pine64 is a pretty cool company too, all of their stuff is pretty community driven and sold with very little markup, and since it all runs open source firmware they'll keep getting updates for a long time most likely (not really applicable to the earbuds unless you manually update them, but still).

Yeah, it kinda sucks how cloud reliant most smart watches are. Like other people in the thread mentioned I think stuff like the pine time, bangle js, etc are probably your best bet for cheaper ones.
There's also asteroidOS which you can flash onto certain older smart watches. It's what I'm currently using but there isn't as much support for it so for more complicated data tracking would require setting up something like a raspberry pi to periodically fetch data over Bluetooth and process it yourself.

This is a project I've been interested in for a bit. It looks like it will have a pretty good feature set out of the box, and with everything about it being open source I'm sure there will be an API for it at some point too. The price is a bit on the expensive side but is honestly pretty comparable to most current gen smartwatches tbh.
I mean the answer obviously depends on what the road is like. Near me, for example, I have 2 different roads that I drive on most often at night, both with speed limits around 35-40. One of them is in town, and has streetlights, stoplights by the crosswalks, and is just generally way better lit. Even so at night visibility is worse, so I'll go like 10 below the speed limit (maybe only 5 bit depending on if I don'y see/think people are out walking or if I'm not as worried about visibility). The other road is basically a country road. It has trees and farm fields on either side, no lights, and is extremely hilly. Because of all that I go like max 20 or 25 pretty much, so I have enough time to brake for a biker I missed when I went over a hill, or for a deer or other animal that jumps out in front of me.
The dangerous thing in a crash between a bike and a car is definitely the car, so it should also fall more on the car to be safe. Not to say a bike has no responsibility for their own safety obviously, but a car should be traveling slowly enough that they have the ability to stop without hitting something if they have a sudden need to, and that means potentially going much slower than the speed limit at night.
