to me, it's perhaps the most difficult corner to make right in current F1 grid.
i'll also put forth some other corners that i personally think are close to being 'too difficult' and tests the driver and car's ability to the max
1. Hungaroring T4 (blind faith in car)
2. Nurburgring T1 (it's a bitch to make that corner without locking, also blind downhill)
3. shanghai T1-T4 (it just doesnt end ... does it)
4. Monaco T13-T14 (swimming pool chicane ... madness)
5. circuit giles villenueve T4 (it looks innocent, but in the wet, it becomes a killer)
6. Monza T8 'curva parabolica' (after pouhon in Spa was sanitized with concrete, this is the last power bend (fastest) left in current F1 with gravel traps)
7. Interlagos T1-T2 (senna 'S') high speed blind entry and plunging downhill ... awesomeness
8. Suzuka T1 (normally not an issue, but while overtaking, side by side it's tricky)
9. sepang T14 (it's always difficult to find the correct line)
10. the whole singapore GP circuit

these are on top of my head are perhaps the most riskiest corners that are harder to get right lap after lap and sorts out man from boys and Red bulls from Marussias.
any other suggestions????
