I don’t know so much about EGS, but probably some of the following (most of which I don’t use very often, I hope I recall correctly)

• Refunds
• Family sharing of games
• Sharing games for other local users
• Being able to lend games
• Remote Play (with friends)
• Remote Play (stream for a local machine)
• Linux support through proton
• probably more?

Freecad is getting more and more attention. When version 1.0 releases (soon), it will be something worth checking out, but there is still work to do.

It depends on the use cases. I don’t like how this post makes it look like the “Linux” alternatives are drop in, one-to-one replacement. Inkscape has been immensely useful to me, but for professional work, it might not be a reasonable replacement.

Actually, a least some cars (probably more than you think)/have some sort of “emergency” breaking signal, which often result in the usual breaking signal blinking for a while. You need to seriously slam the brakes to see it though. E.g: https://m.youtube.com/watch?v=j_osu1WgGMU

There is also a nice technology connection video talking about braking lights for electric cars and in general, which can be dangerous.

As a first step, I would recommend checking out osm.org from a computer. Once logged in you can use it as an editor straight from the browser. The embedded documentation really helped me initially.
