I think you got concept down nicely with the driving horror. It definitely has some potential to expand on making it more difficult for the player to keep their focus on driving while also distracting the player with external events. Obviously there is some polish needed to the game and for the player experience like control instructions or a clear ending point to the game. The driving itself felt pretty relaxing as I personally like driving games and to use the mouse to steer the wheel as opposed to the traditional AD keys plus a pixel hand to give player interaction feedback i felt was a nice creative touch that you definitely did a pretty good job on.
