Build me a simple browser game inspired by Slow Roads, just for a personal demo. I want to open it in a web page and drive endlessly along a calm road with simple scenery, smooth controls, and a relaxing feel.

Keep it lightweight and easy to run locally. It should have a main page, basic car movement, road generation that keeps going forward, and some visual atmosphere like sky, ground, hills or trees if that’s reasonable. Add keyboard controls and a small on screen note telling the player how to drive.

Please don’t copy the original game or use any restricted assets. Make an original version with the same general vibe of a peaceful endless driving experience. If you need current browser graphics docs or examples, look them up online.
