Bernie is just a complete nut job who is not getting any better the nearer to imortality that he gets. Its about time someone on one of his various boards of investors woke up, slapped him around the face and told him to f**k off to the mental home. Wet races are not fun, they are just slow parades that do nothing to showcase the technology and excitement in racing and the Pirelli guys statement that simulated wet races wouldnt be a problem as there would be no clouds is a ridiculous statement to make, what happens when its blazing sunshine and the drivers cant see the track for reflected sunlight and all the other associated problems of driving in the wet with full sunshine?
Sure these plans might mean that more people crash and it changes the grids a bit but if you want to watch that sort of racing you can go and watch the feckless idiots who do touring cars or even formula ford as both series have far more of what Bernie seems to be after in races that take a quarter of the time to complete at a fraction of the cost. The whole thing about F1 is that its supposed to be the best drivers in the best cars in the world who are at the mercy of the conditions they are racing in, not a bunch of amateurs driving around in multi-million pound cars.
Saying all of that, the manufacturers would soon tell him where to go if this became a serious sugestion.
