@vitux what are you asking me here?
We already have the excellent article above about how the road is calculated, exactly how it is rendered on the screen on an Amiga could be various. It could be blitter filling, or it could use the hardware technique using copper and scroll registers, effectively the same as parallax scrolling. The "stripes" of the road and grass are certainly copper palette changes.
The roadside objects and cars, I am sure, are simply bobs that have been pre-scaled to different sizes.
