title: Open-source urban driving simulator
body: <p>Open-source urban driving simulator needed to build an automated taxi driver. The dream feature-set may include:</p>
  
  <pre><code>* easy import of external AI code
  * other agents, such as cars and pedestrians
  * simulated programmable traffic and traffic regulations
  * relatively realistic physics engine
  </code></pre>
  
  <p>I had a look at TORCS, which has most of these features, only simulates a racetrack. Any suggestions are highly appreciated.</p>
