Really good game and good urban legend you made for it.. At least I think so, because I was trying to find something about that legend but couldn't find anything.
Just one thing: As somebody previously said, it is hard to figure out what to do after you "loose" the game. Maybe you could implement there something which will force the player to stop in front of the woods. I was thinking about some scare, but that would ruin the buildup. Then I figure out that you could made it just like that. Like to force the player to stop, nothing about it. Maybe like the engine will suddenly crash and the car will stop moving for a second, until the engine will start again. So he will have a time to look around and see the opening into the woods. But make it after some second or third round-around, when it is clear that the player is loosed and doesn't know what to do, otherwise it could hurt the atmosphere if it is made right straight away.
Anyway,, good game, I enjoyed it and gave you a rating of 5 stars
