Just binge watched Season 2 of House of Dragon before Season 3 starts today.
I noticed the aspect of the size and mass of the flying dragons with the wingspans. Realistically, they would have to be cruising at over 200 miles an hour to stay aloft. In a dive from a good height, they should crest 450 easy.
The dragons can handle the G-force. The rider would be blown off from the airstream. The wooden seats and rope/leather straps would fail. I don't think the rider would be on the dragon in a high dive.
A rapid climb would put 7 or more G's on the rider and seat carriage. G-LOC would happen and the rider would let go of the straps. The seat carriage which looks like wood would probably snap off taking the rider away.
In case there are dragons hibernating in caves undiscovered, the only way to be a successful dragon rider is to eat your can of spinach beforehand and have a titanium seat harness with polycarbonate straps.
Entertaining stuff to watch but pure fanatsy.
