There are so many ideas in your article, Paul, that it would take a long message to reply point by point. I agree with the reduction of downforce, it's almost ridiculous to see cars take Eau Rouge flat out nowadays.
This may be off-topic, but with the possibility of racing being delayed until July or, more probably August, I think the current season should simply be cancelled. I don't think that a driver would really like to be crowned champion after a season of 10 races. Can you imagine the endless discussions about the real worth of that championship?
Instead of a championship, when racing resumes, why not have a number of non-championship races? Maybe 8 or 10? There used to be non-championship F1 races before. So, let's race at Silverstone, Spa, Monza, Suzuka, etc. There could also be a race at the new Zandvoort to try out the new layout. And since these would be non-championship races, with no points in play, F1 could test some new race formats. All those ideas that were mentioned recently, like reverse grids, qualifying races, etc. could be tried out. And maybe have a few races where teams could run a third car with the reserve drivers. That could result in a 24, maybe 25 cars grid.
That way, each race would be an event and I bet you the TV ratings would jump. And for the fans, it would be a nice change from the routine of conventional race weekends. Then, a real season will take place in 2021.
