It’s important to note here, that in Germany (at least, the region where I live) you will fail the practical driving exam if you don’t stop at a crosswalk with any pedestrian within about 5 meters, unless they are actively walking away from it.

I think overall German driver’s education is significantly better (and much more expensive) than in the US.

Depending on the language, there might exist an automated tool for generating those kinds of diagrams from code.

Nope, David Revoy does a lot of comics in this art style, and the Avian Intelligence parrot has been a recurring character in the last few.

I can also really recommend his comic series Pepper & Carrot, it has some very cool worldbuilding.

This one isn’t super well known, but for small projects I really like raylib, and raygui. It gets impractical for complex GUIs, but it does make it really easy to quickly start something from scratch.

Edited my comment to fix, thanks!

This is less of a source and more like a compilation of resources, but for anything spacecraft related I can always recommend Atomic Rockets. For this specifically, the page on Heat Radiators.
