i think what makes a good roadtrip song is it's easy beat feel good vibes like this one from saijaku tamer wa gomi hiroi no tabi wo hajimemashita

but a great roadtrip song is marked by its relatability and shared nostalgic feels; it is a plus if everybody or most can sing along with it. here is a great one from yuyu hakushou for people around my age.

You may be right. It's much fun if everyone knows the song so they can all sing along. 😅
karaoke na yan. bwahahha
Both are good, I love more the second one though. Though I haven't really watch it, but it's familiar to me as I used to listen to it YT.
it is a very old anime, shown at least 20 years ago. but it recently had a live version shown in netflix.
