I like the twist "you are the corrupt copilot" as it fits nicely with the theme. The goal is silly but it definitely has its charm and although there is no clear visual guide at all, the voice lines really do the job of helping you get out off the road!
One thing i should consider is that once you know the gimmick, it can get a little trial and error as you can get messy with the controls and still win, but i guess that was a design choice. It definitely has potential and i would like to see more of it.
