As an AI language model, I can help you with creating a simple game in HTML with JavaScript, but please note that creating an open-world game with insane graphics and real-life cars is outside the scope of a single HTML file and may require more complex tools and frameworks.

This example sets up a canvas element where a blue square represents the player. You can control the player's movement using the arrow keys on your smartphone's keyboard.

However, this should give you a starting point for building more complex games using HTML and JavaScript.
