Another thing, when you pass the railroad crossing it's a little lame, try to move the camera towards the car as they pass so it looks like the train is going at them, you could use a bike or so I guess.

About the end, you could simulate damage by parking the car 45 degrees to a wall, open the hood a few inches and screw the indicator loose so it hangs by it's wire.
It would be convincing if there comes somke from the engine compartment but I don't know how you should solve that in a good way...
