Für kurze Strecken das Fahrrad, vor allem, wenn ich durch den Wald fahren kann.
Für längere Strecken der Zug aus ähnlichen Gründen, wie du es beschreibst. Ich liebe es einfach, mich dort zurücklehnen zu können und mich um nichts kümmern zu müssen. Die vorbeiziehende Landschaft zu beobachten, Podcasts oder Musik zu hören, zu lesen, die Augen zuzumachen... :)
There is Goldfish, which was started with beeing some sort of TikTok alternative in mind. But it's stuck in a very early stage and doesn't seem to be developed anymore. If I remember correctly the Admin started it as a practice for themself to get more into Activity Pub.
They have a Mastodon account and a github page, maybe you can ask them there if they plan to develop it further. And since it is open source and can be forked by anyone and everyone can contribute to it, maybe someone will be found who is interested in continuing to work on the project.
On Goldfish's github page I also found Vidzy by accident, where developement seems to be more active. However, I found no active instances so far where one could test it.
