KhazP/librecorsa ? reverse-engineered prompt

Build me a browser based racing simulator that feels like a serious motorsport game, not an arcade racer.

I want it to run entirely in the browser with no install, and load as a static site. It should have realistic vehicle physics, tyre wear and temperature, weather and changing grip, a proper race start, AI opponents, ghosts, lap timing, replays, and peer to peer multiplayer. Make sure it works with keyboard, gamepad, touch, and force feedback wheels if available.

Include a few cars, ideally an open wheeler as the main one and a GT3 car, plus a handful of real feeling tracks. Add a simple garage or setup screen, race weekend style menus, and a clean HUD with speed, lap times, sector gaps, and position. If you need to check current docs or browser APIs, look them up online. Keep it polished, fast, and playable, with the feel of an open source sim people can actually race in.
