No hills? No banked curves? No suspension?

Unreal Engine comes with two car demo projects. The first one is the "Hello World" of Unreal, and has a simple vehicle. The second one has an actual suspension model.

At the end of the talk, and article, there is a short video demostration of the current state of the game engine, and it has hills and banked curves and whatnot. For the talk I opted for a flat grid.

Suspension is implemented as well but it didn't feel to me like a unique problem to implement for cars, at least not a simple suspension that can carry a car, and it didn't fit too well with the flow and limited time I planned for this.

Wassim said in talk's QA that suspension is incidentally handled by the physics engine, which feeds back into uneven tire load, affecting tire forces.
