After all the discussion last year, have they figured out a cockpit cooling solution? Cockpit temps were a non-story this weekend.
They have quite a range of devices now. (see below) I don't know if any are mandatory (other than item 1), but it would make sense at the hotter races as some solutions generate a bit of drag. I remember at one race last year Will Power was lamenting using the upper-scoop (4) as he felt it cost him a bit aerodynamically to his rivals who made do without. In that scenario, if there was a risk of drivers overheating, i'd hope the series would step in and tell everyone to use them instead of them making that sort of risk assessment themselves.

1. NAPA, sorry 'Naca' duct
2. Nose ducts. In my day, these were known in F1 as 'donkey dicks' due to the long hose/duct feeding into the cockpit.
3. Helmet duct. These just ram airflow into the drivers helmet. Most drivers seem to use them.
4. Upper Scoop - This just re-directs a bit of passing airflow down into the cockpit. First seen in Iowa last year but occasionally popped up at other races.
