Pirelli are sure to keep us informed about which actual two compounds they are taking.
I don’t really remember Bridgestone doing that last year. The compund schedule was released, but it was usually several races in advance, and usually only online. By the time the later races in sequence had come around, I’d forgotten which compounds were in use. Pirelli’s system not only makes it easy for us to remember which ones are which, but it also helps spectators at the race, who may not get commentary. I was at Homebush for the 2009 Sydney 500, and every time the cars went by,it drowned out the tannoy system. I can only imagine Formula 1 cars would be worse.
