Jason, excellent job!!  I managed to play to the end, despite my terrible game driving skills, which the attached pic demonstrates!!  (Not meant as any criticism of your game -- just as I said -- it shows what a lousy driver I am).  I thought I was permanently stuck here, but after the screen capture I was magically unstuck.

As for constructive criticism, I do think the car could go a bit faster.  And it needs to be raised up a bit, the tires seem to not be entirely on the surface of the road.

Could you tell me if you got the city terrain from the SketchUp 3D Warehouse?  I've tried downloading some very large terrain objects into SketchUp from the Warehouse without success.

I want to make a similar driving type game based on my hometown's downtown area (Kansas City).  I will download the buildings individually and use the existing racetrack object that comes with 3D Rad.  I am not sure how I will deal with the height of the walls on the race track, however.  I would like a more ordinary street, instead of a race track with the walls.

Does anyone know if there is a way of extracting terrain from Google Earth and importing it into SketchUp?
