Uh... he fell asleep with his hands off the wheel? Okaaay...

Anyway, Suzuka x Spica's Trainer (AKA Okino T), #2 popular Suzuka pairing after Sweek. Even has a shipping tag (well, two) dedicated to it on Pixiv and Nico. Usually one-sided though, with Trainer being nearly completely oblivious.

Sometimes this gets turned into a chain of one-sided crushes with Sweek pining after Suzuka and then Grass pining after Sweek...

Probably stopped at a rest station. This scene is a reference to the season 1 episode 7 trip, which I assume is a long trip.
