You're complaining about the very first corner of Singapore?
Are you sure you don't mean Turn 10, the "Singapore Sling" - that chicane at the very bottom of the circuit? If so, it's there for good reason: there is no room for run-off on the outside of the corner. The chicane is there to slow the cars down, because without it, cars would be approaching a corner with no run-off at high speed.
There's another problem too.
Half the people are looking at just these tracks because they're newer to the sport.
The other half remember those tracks from the 80's and 90's, and think that the only good tracks are those jewel races.
LiquidAs a fan of Formula 1 since 1997, I disagree with this. Anybody with a modicum of sense can see that Monaco is a bad track, Spa and Hockenheimring have been neutered and Monza has longevity, but is not necessarily a brilliant track.
And I personally don't like new Silverstone.
LiquidSepang is a Tilkedrome, and a damn fine one at that. It's the perfect return to someone who claims that everything he does is terrible. Brilliant track.
Advances in safety.
We can look at 1980s Silverstone and say, "Wow, it was so much better". But if you were to imagine being in the 80s, people would be saying, "Well, it's nothing like it used to be in the 1950s. Chopped and changed for the worse".
And while I personally liked it, old Hockenheimring was a test of engine endurance, which would yield pretty bad races in this age of bulletproof V8 reliability. But if I remember correctly, Hockenheimring was also changed due to safety. The marshalling access roads from the Nordkurv to the pits were poor. It became too outdated to maintain, with sections of the track in rural nothingness, much like the Nuerburgring.
