What I liked about the circuit part is exactly what Porter said. That they didn't place any chicanes/artificial stuff on the circuit itself. Specially the long turns of the first stage were nice to watch. Combined with the nice and tricky sections on normal roads it was cool. But off course wouldn't be nice to have whole stage on the circuit.

Basically the stages showing the whole point of rallying. The can drive like crazy on normal roads..and it can do that on the circuit as well.
