Hi everyone 👋

**Roadarium** is a browser driving simulator built with three.js from OpenStreetMap data. It has 119 real cities, including London, New York, Paris, Tokyo and Kyiv, with traffic, trams and pedestrians that follow each country’s rules, on the left or the right.

It’s meant for learner drivers: make a mistake and it shows you what went wrong, with a replay.

**▶ Try it:** [https://app.roadarium.com](https://app.roadarium.com/)

No install and no sign-up. It runs on desktop and on phones.

A note on how it was made: the code was written by AI coding agents, while I directed and tested it. So I can’t go deep on implementation details, but I thought it might be fun to drive around your own city.

It looks fun, but the world map is quite off. You need to make your AI agents to do a better job.

That is intentional, it did a great job. It’s easier to place many more cities with labels.

Looks interesting but lacks a score counter

I kept hitting pedestrians but my score didn’t show
