Formula one hit 200 in-race in 1980s and haven't gone much higher since.

Obviously there are tons of factors (regulations, purpose, etc) that affect these, but did you expect some constant , linear increase?

My point wasn't that speeds haven't increased. In fact the opposite - they do increase, but at slower pace as they've been hovering around the practical ceiling , as opposed to the theoretical /no-holds-barred ceiling.

Jet fuel costs a lot more and per/pax revenue is a lot less. There's no point in designing or operating a commercial plane at faster speeds.

Just like there is no point in designing an f1 car to reach 300 when tires and fuel capacity won't sustain that speed
