Two things:
1. Compare/Contrast this Car Gameplay with the Batmobile in Batman: Arkham Knight and see how things go for future.
2. Seems like the Drivebelt called "Nomura" broke. And now they're trying to take it to the nearest repair shop to get it fixed. *joke*
Seriously though, Nomura's been working full blast on this thing for years and hasn't done much with it, so it's expected he'd be overheated.
I'm sure Squeenix maybe thought he was taking too long too and sat him on the bench for now. (Like relieving a tired Pitcher in the 7th Inning Stretch).
