Collision detection

Love the updates with on-line Drivey and the new environments. I did much prefer the original Drivey traffic though to look at, especially the night-time lights on the cars.

Optional collision detect would be lovely too.

Drivey cars are in development— I'm making a car generator, that produces random variations of late 70s boxymobiles.

If I ever get around to collision, it'll likely be by moving all the physics to a box2d simulation. I'm honestly in no rush to implement this, but it would indeed be nice, and probably not too difficult.

Just to add.... I've changed my view a bit on the traffic. I do really like the colourful spheres now - alongside the idea of boxy 70s cars (I think Volvo with my European head). Be great to have both somehow as an option.
