So it's a combination of the halo device (red oval) and this extension that I mentioned (green oval — forget about the doohickey on top which looks like a Google Street View camera), both of which, but particularly the latter, are not aerodynamically optimal. That and the five-point harness, sacrifices for safety.
I would still prefer to be a NASCAR driver, though.
EDIT: That extension, does it double as an engine air intake?
EDIT 2: Wow, that halo device has not been around for very long. Early development was spurred by "In 2009, 2 major accidents happened in top level FIA open wheel series, the fatal accident of Henry Surtees at the Brands Hatch round of the 2009 Formula 2 season and the accident Felipe Massa sustained during qualifying at the 2009 Hungarian Grand Prix. The accidents led to calls for additional cockpit protection". It has been in general use only since around 2017.
EDIT 3: The Wikipedia article alerted me to the existence of Formula TWO racing. I will not exhaust your patience, inquiring about the difference. Instead, I will follow links.
EDIT 4: Ah, sort of a junior or minor league. "For much of the history of Formula One, Formula Two has represented the penultimate step on the motorsport ladder."
