I have a variant where I did that, but ended up saving maybe 20 tiles (according to ProMotion NG). For a simple demo I decided to leave it. When I get around to adding sprites, I expect I'll have to try to minimize how much I'm wasting with the road.

I just drew a road texture in ProMotion NG, and animated it with Python. The forward movement is a bunch of calls to VDP_setTileMapEx(). Which might be a bit wasteful (haven't checked what happens with empty tiles).

code is in my github repo github.com/radioation/M...

It's actually surprisingly simple from a coding standpoint. I randomly saw "Street Racer" for the first time a few weeks ago and wanted to figure out their roads. They seem to just have the tiles pre-rendered in Video RAM and use them to fake forward movement.
