Your right, I'm sorry about that I made an edit to correct it.

Thanks for asking i've been wondering myself actually. I looked it up and organic maps doesn't actually do traffic, although magic earth does (another not foss but apparenty privacy respecting map app that uses osm) It says it's just crowdsourced from the general public who uses magic earth (in an anonimous way, I guess there are enough magic earth uses for it to work since Some people say it works really well. (although others say it doesn't you should probably try it for yourself.)
On another note that I also found from my research just then, traffic knowing apps don't actually improve travel times but they do make previously congested places more congested. sources:
Edit: Magic earth is not foss so there is no way to varify that the app is actually respecting your privacy like it says it is, i'm sorry for any confusion.
The asci video player would be cool. I don't need to go to my web browser to watch youtube, I could do it in the terminal! terminal spotify client also seams cool, although I wouldn't know where to start with that. I could just make an mp3 player, it would align with my idea of privacy. What do you mean by ebook converter? does it convert physical book pages to ebooks? i'm slightly confused.
Also I love the cli based ideas we need more cli apps.
The construction cite issue is a fair point. If you really need traffic maybe you should try using magic earth. It's not FOSS but the privacy would still be leagues better than Waze (which is owned by Google)
