Very esoteric app, however I think Ymusic needs to be mentioned whenever YT alternatives are brought up. It streams only the MP3 of the video and the UI is cleaner imo - so it's easier to use if you intend to only listen to "podcasts" or music as an alternative to Spotify.
This is just begging the question: surely you don't watch videos while driving? And if you just want the audio, there are music-focused YT apps (ViMusic, or like sibling said, YMusic)
Newpipe has a built-in "Play in Background" feature that would be awesome while driving. There are tons of podcast-like content videos on YT that would be fine for a commute.
