This was my dilemma too! It pretty much eliminates all the Pixar movies, and Lilo & Stitch.SAFD:
Since you specifically said to watch on a trip I would have to remove any of the movies that would make me cry (looking at you, Up!)
Who Framed Roger Rabbit? is a great movie to watch when I'm on the treadmillSAFD: Fantasia, Aladdin, Who framed Roger Rabbit?
Was tempted to have Encanto on the list but still too new.
My son went through a big Cars phase (still is in it, tbh), and I was able to tolerate the movie a lot more once I realized it's basically a reverse Hallmark movie. Guy leaves the big city, gets stranded in a small town, and learns about life and love.SAFD: Emperor's New Groove (shouldn't come as a shock given my avatar ), Inside Out, and Cars. I just never get tired of any of these.
