I already tried this, but if you rotate will make in some directions the collision will be wrong due the car perspective.
I mean the collision box have to change in each frame to get perfect to the car. Example:
So, to get that or something aprox to this i will have to do some kind of maths to do a collision box in a sprite and after that: Every tick > Rotate + set X width/height to transform
And i don't know if this will works, still i have to play with that idea.
This will be more easy if Construct will also have some "guess polygon box for each frame" so with the shadow pre-render i apply that and in a second i have what i need.
