chavm, I am really sorry but you should be the last person telling somebody to stop posting...
But to stay on topic
The Hilke Tracks have two advantages over older tracks:
1) The attending audience can overview pretty much the whole track from everywhere. Thus, for the people there, it's better than an old, hilly track.
2) They are safe for the drivers, because they have lot's of run off areas, no blind corners and are easily accessible for rescue teams. Thus, they are better for the survivability of the drivers.
But now comes the point which renders the suggestion pretty useless: We neither have live audience that is restricted to a certain place from where they have to watch the race, so there is no need for the track to be in good view from every angle.
Nor can we, due to the nature of LfS, be harmed while racing, rendering the second merit useless.
So what we basically have left after the main selling points don't apply here, is a quick, boring to drive, boring to look at track. Now, if I would want to get bored i'd watch Formula 1 but not drive LfS.
So in my humble opinion the only point speaking for adding such a track is because nowadays all modern tracks are that way and the devs would want to have one in game for the sake of having a modern track in LfS.
