Here is a good one for people to ponder about. Since last season I have noticed a particular design trend that has been spreading among teams. It has to do with part of the sidepods. Don't have enough time right now but hopefully tomorrow I can create a full length post explaining my observation and how I think it affects the aerodynamics on the cars that this trait has been applied to.
Maybe last season somebody talked about it and its effect but I haven't personally seen it. I was wondering if McLaren would adopt it this year and it seems they have partially done so. I also want to wait for the other cars to be released to see how many other teams have a similar trait on their sidepods.
