Cool take on the theme. I had the same experience as buzzyard regarding full screen & ultrawide, but I have one of each, so I pressed alt+enter and got out of full screen, then went back to full screen on my standard HD monitor and it worked fine. In Unity, I think what you'd want is to take "free aspect" off and pick 16:9 to fix this.
That out of the way, I could actually have some fun! It's entertaining once you get going. A couple of things I'd be aware of is that the cars colliding into you from behind happens a bit often. I had some hit me when still counting down, which was inconvenient LOL. Also, a counter to this might be the rear-view mirror, but the cars that are coming up are not "mirrored," so it's disconcerting to use that. Flip that around and I think you're in good shape!
