@hashemi I am a bit hesitant to publish it, because it is a learning project - I am still new to rust and this code is not much prettier then the original (though I gave my best when naming the variables). But I guess there is no shame in learning and not being perfekt. I'd be glad to hear feedback.

Here is the repo.

@hashemi I just added the scaling to my implementation (I had just not used the overlay until now, instead I drew onto the collision map). It was interesting and I definitelly had to iterate over it multiple times.

My bigest realization was that it is not enough to just adjust the position of every car pixel. That would spread out the cars pixels over a bigger area, making it less dense. The scale really has to get into the car length and car width before you iteratate over them.

Your problem persists, of course. I decided to make the cars thicker in my simulation, so this is not as big of an issue anymore.

I realized if you don't specify an overlay image file, the code will just create a blank PPM file that is 12 times larger than the map.

In case someone is interested, I just made my Swift port public.
