I think the car being the same color as the Swedish flag is a coincidence. After all, the Banco do Brasil logo is on the sidepod.
It is interesting that the driver uniforms are still in Sauber gray-white. The Banco do Brasil livery on the car, and logos on the uniforms always seemed very last-minute to me — gives me the feeling they could go away at any moment.
Joe, off topic and please excuse the impertinence. I wonder if you could discuss, probably in GP+ I would suggest, the issue of drivers being called upon to lose even more weight before the season kicks off. Several have gone public on this already. It seems to me this is a very real safety issue. The harm Jean-Eric Vergne did to himself in 2014 is cited. And the answer, as far as I can see, is simple and has no downsides. Mandate a suitably ballasted seat so that the seat/driver weight is the same in every car. Fairer and safer.
