The Bucharestring is running around the Parliamentary Palace of Romania, one of the largest buildings in thw world. When using the time traveling otion you can see a picture showing the track in preparation. Best thing is to use this tie travel option to see what the track's like, If you'd do this at Suzuka you could find an unclouded image too. The final turn is a roundabout like turn.
The Guia circuit is similar to a combination of Monaco and Hockenheim. It has a hugely long front straight with two kinks in it. On the other side of the track there's this slow, narrow section with one of the worlds slowest hairpins. It is used this weekend so you should be able to find enough information. It's one of the few street circuits with permanent pit facilities making it not temporary but semi-permanent.Added (2009-November-21, 11:14:41 Am)
