Sadly this is exclusive. "Udacity Universe offers virtually limitless opportunities to interact, collaborate, and problem solve, and is exclusive to students of our Flying Car and Self-Driving Car Engineer Nanodegree programs."

I can hear a single plane or helicopter miles away. It's going to take massive improvement in noise dampening to have roads of flying cars. Not to mention all the other challenges.

  As far as cars are concerned, above ~30km/h, the noise produced by air resistance is louder than the tire noise. Cars, however, are on the ground, i.e., surrounded by massive sonic breakers (i.e., buildings). It should be quite difficult to have a large amount of flying vehicles without an enormous noise impact, unless they're flying very high.

    Could somebody please declassify those silent UFO engines? We need them for the environment! /s

    This seems like an odd claim. I've watched quite a few gliders landing at an airport and you never really hear them. Is this really true?

      I've done glider pilot training and gliders are an aberration as they are built to be supremely aerodynamical. Yet, once you go high speed (>100km/h), they are noticeable and at 140km/h they sound like an approaching storm, so you definitely won't miss them nearby.

Are there any driving simlators with accurate (as much as possible) world maps? It would be so nice to practice driving around Boston without fear of getting lost in random one way streets or picking the wrong turn on five way intersections.

  Looking at WRLD it appears to have some fairly accurate cities - the pictures of London looked fairly accurate - but only saw a couple.

  WRLD is a 3D model of the world based on a real world coordinate system, including building heights. The platform has a good chunk of the world mapped but continues to add new areas based on customers. Boston is included!

Wouldn't photo-realism here be nice? The Microsoft simulator is a little more photo-realistic[1]. At first glance, WRLD looks a little cartoon-y. Wondering if anyone's tried this? [1] https://www.youtube.com/watch?v=GB-sBpXvM3s https://www.youtube.com/watch?v=GB-sBpXvM3s
