Police chasing with TikZ
Here is a first version. I was not aware that the rounded corners had such an impact on the tangent slope. My bad, fixed it

just for fun and to expose my point, I use the recycled code to draw the road from Drawing street curve, then doing the positioning node in a path including an image, in this case images transformed to svg edited in inkscape and exported to pdf format, you can access these files on my drive, available until the big G disappears, consists of 4 sprites 2 for each car, which I alternate in a certain frame.
RESULT:
MWE: To run you need to download the pdf files Sprite-police-side.pdf,Sprite-police-front.pdf,Sprite-car-front.pdf,Sprite-car-side.pdf, or any tikz pdf output, inkscape pdf output,etc., to the forder where the main .tex file is saved.
