So according to AS today:
During discussions between teams and Ecclestone at the Brazilian Grand Prix, one idea put forward was for a two-tier F1 to be created in the future.
As well as the usual constructors, the grid could be filled with upgraded GP2-type single-make cars, which would be run by customer teams.
Now this is immediately controversial, however I like it!
This year I started to get into the WEC, I've sort of been on the fence about the mixing of classes for a while but realised that I've never really sat down and properly watched a race. When LeMans rocked up this year I was absorbed, fascinating racing with multiple battles and winners. I loved both cheering for the Porsche and OAK in LPM2 brilliant.
So my views on mixing the grid up have changed, and maybe this is a great way to get more cars and drivers on the grid.
