Whether or not the prospect of 24 races appeals, how about more teams? That was the tantalising post-2020 prospect Ross Brawn dropped in casually during an interview with Sky Sports F1 recently - which was followed by news of some actual proposals, which then got short shrift from F1 itself.
We chewed over the notion of new teams with F1 Racing columnist Mark Gallagher in the latest edition of the Flat Chat podcast. His verdict was eminently sensible: given the state of F1's commercial landscape it would make more sense to buy in to an existing team than set one up from scratch, but if you really want to go to all that time and expense, then... knock yourselves out.
Brawn described the number of entities who have expressed an interest in joining F1 as "surprising". Is it really? Last time the FIA threw open the gates to new teams it was overwhelmed with pitches for the three (later four) available slots. But let's not forget mid-2009 was a politically febrile time; I remember doorstepping the late Martin Birrane (on his way out of the toilet in the Le Mans media centre) to gather his thoughts on Lola's exclusion from the final list, and many of them remain unprintable.
