Feels like Tuesday afternoon on my local highway.
Really though, hilarious game, I laughed out loud watching the cars drive off the road ahead of me. Fits the theme really well too. One minor complaint, it would be nice if you had some kind of reset or "unstuck" button, since once I did get stuck on the edge of the roadway and had to close the game and open it again to actually complete it.
Other than that, simple and funny and enjoyable, good job!
