I wouldn't say it's impossible, but it would be quite hard to get it to flow just as well. Forget about Physics engines. They're too expensive (CPU wise). A little quick and dirty math will give you what you need for the driving / collision detection. Using Away3D Lite you could display more textured triangles, but I have a suspicion that you would soon need many of the more advanced features only found in the ordinary version of Away3D.
