have a couple of completely soaked corners -
This could work.
Basically it would be like having a hose pipe left on and a steady stream of water trickling down, completely soaking the corner.
The problem is that I don't think it would be a good idea to have only a partial (fake) wet race. If you are going to advertise and market a particular GP as a wet race, you really need to soak the entire track. This way, the fans, get what was advertised...ie. a completely soaked track.
The media hype surrounding an artificially wet race would be MASSIVE, as I don't think (somebody correct me if I'm wrong) it has ever been done before and only F1 could afford to do something so lavish and outrageous.
I think Bernie is really aiming to increase TV audiences, in a time when all sports are adapting to the times, to compete for TV audiences. I was watching the Cricket World Cup on the telly a few days back and things have completely changed. The game has become so much more exciting and spectator friendly since 10-15 years ago. They have lots of technology, colourful team strips, powerplays, etc. The game is far more exciting than it ever was.
There are some F1 purists who feel that F1 should be allowed to continue as it has done for decades, but this cannot be allowed to happen. In order to make the sport bigger or at least hold its currentTV audience share, it needs to come up with gimmicks which will draw casual watchers into the sport, in the hope that the casual viewers will get hooked and become regular viewers.
F1:
has already increased the number of races,
is now hosting races in countries which have never had F1 races before
is now having races at night, under night lights
is now more time friendly to European audiences
is now introducing gadgets/gizmos to make overtaking easier
The next logical step is to start having 1 or 2 artificially wet races. At first, it shall be experimented with. If successful, then it shall become a regular fixture.
