I missed 2010 Korean GP, got my real first look at it. I kind of like it, i would vote that as one of Tilkes better days. It has one straight that is long enough for good drafting and i can somehow give those two hairpins a reason to exist. Not the most elegant solution but effective and simple. Badfor drivers, the rhythm gets lost there but once sector 2 begins to flow to sector 3 it gets very good. The street-section is a good idea, even if it feels a little bit forced. Lacks a little bit of attitude and character. If they get to finish the streetsection someday it could give it the necessary spirit.
Not the worst Tilke in anycase, that honor goes to Abu Dhabi (and to the amateur owners that just have too much money...) Track that works only with modern type of F1 (or other modern high powered open wheelers..) is a sign of bad track design. There are a lot of tracks that these F1s can't drive in anymore, they've evolved to another state of racing and needs new kind of tracks. IMHO F1 will need a new concept very soon, maybe a lot less aero efficiency, more drag and enough small bore turbo power to make the Earth tilt in it's axis.. But some really radical changes, semi-open wheels maybe?
If they just changed one thing in all of the tracks: make a complete 180 and return to the old gravel traps that let the cars sink. These new mall parking lots they install at every corner have reduced the cost of small mistakes to almost none. It's much less demanding and more predictable, just what teams want. They don't like extra variables and FIA haven't realized what it does to the races; every car finishes and positions don't change much as every mistake can almost be erased from the lap times. Instead they installed KERSPLUSDRS and changed the tires (that was a good move..) and ruined a lot of circuits trying to make artificial passing points taking all the oomph from old school HC tracks..
They should've keep feeling of danger closer and we would've seen some Vettel DNF's, Hamilton getting stuck in grass for every race etc. Some randomality is essential to motor racing. I'm not expecting a huge race this weekend but anything can happen, there are some places that have been designed very cleverly to allow a little difference in racing lines between defender and attacker. If there is only one way around the corner it limits the space available, two cars won't fit to excact same location in space/time. Somehow i get the feeling of Australian / Canadian GP circuits. I like them both..
