Do you actually have to produce some c/c++ code at the end or is the implementation up to you?

If you are free regarding the implementation I'd take a few shortcuts and implement it in blender game engine http://www.blender.org .

Get RC Car game demo(Racer25.zip) from: http://mikepan.com/files.php blender artists tread: http://blenderartists.org/forum/showthre...e-work-log .
It will run with the latest blender version. Disable ghost property on car body to allow collisions with the environment. Replace the car mesh with a realistic one(maybe mikes BMW3GE.blend). Separate braking from reverse driving. Adjust the car camera offset to be inside car at driver position.

Find a road section in real world, make photos of the building facades, road surface and recreate it in blender using the photos as textures.

You can use makehuman to create a high quality human mesh http://makehuman.blogspot.com . Import it into blender. Use photos from a friend as textures for it. Use a blender version with motion-capture toolset http://vimeo.com/28005237 . Animate the human mesh. Place human mesh in the game scene and trigger the animation by a sensor.

You will have to figure out how to add sounds. I'd look for blender game engine demos with sounds http://blenderartists.org
