However it should be said that a 25mph road should really be designed as a 25mph road, with suitable traffic calming measures. Far too many low speed limit roads are big and wide open, practically encouraging people to speed.

Sorry, but this is nonsensical. The wide road did not make that cop drive 75 miles per hour in a 25 mile per hour zone. That officer was responsible for his own actions, and would have found a way to drive at an unsafe speed regardless of how the road was designed.

I take on a homelab or Apple ecosystem project every weekend to keep my skills sharp. What I’ve noticed after several years of doing this is that I know a whole lot more about what the homelab services can do than I do about the iPhone in my pocket. Today, for example, I forced myself to go through the Health app and enter things like medications. Pretty soon my devices were reminding me to take my medication and asking me to log what I took. Despite all the reading I do about Apple products, I didn’t realize that the app would remind me to take the medication. That’s really useful!

Another example is when I learned how to make the iPhone make white noise. Who knew that the accessibility features included that? Or that you can choose ocean waves or rain instead of the white noise? And here’s something I learned entirely by accident when trying to pay for something at the store — pressing the sleep button three times toggles the white noise feature. I don’t think that’s written down anywhere.

This is why I need some of those in-depth tutorials. They always expose you to a dozen tangentially related capabilities while you’re learning about the subject of the moment.
