You said it wont move, You've enabled the "no user control" flag. That might be your problem.
I also found your rotated car problem.
Here is why it wont rotate properly: You have to change the pitch of the path_tracks. The pitch has to face towards the way you want the front of the car to face, if the next path_track is upwards on the grid, point the pitch upwards etc, make it point towards the next one, it turns appropriately to the pitch. Also change the first path_corner into path_track, corners are for func_trains not track trains.
Edit: Here, that
should work for you. experiment with the pitches. I took the liberty of moving the van since it was in a tricky angle.
