At Button's second stop, the jack man circumcised the um, appendage protruding out the front of the Mclaren. When asked about it after the race, Jenson said he was cold for the rest of the race. He finished 4th 3rd. Whatever. In just about every race driver say that they're hot, they haven't got enough water, they're sweating, it's really hard to continue...
Might I suggest that they just get better air inflow into the cockpit. If a jackman can do it, imagine what an aerodynamicist could do. Maybe with a diaphragm, or valve? I know that the package is tight, but, you know, be nice to the driver??? It doesn't seem to take that much to let your driver chill whilst they are driving...
