Everyone here is correct about power being the biggest limiting factor.
The number 2 factor though is concussions.
Concussions don’t usually happen from something slamming into your head, most concussions happen from your head moving quickly and then coming to a sudden stop, and your sloshy brain inside still has momentum and slams against the inside of your skull.
It’s why you can get badly concussed in something like a car accident even if your head never hits anything. Or in football / hockey, even just a big full speed hit to the chest can give you a concussion.
The way Tony Stark moves in that suit would give him constant concussions. You cannot move that quickly and suddenly come to a stop. Until we have a way of transferring consciousness to a computer or something solid state, theres no chance of ever directly piloting an iron man suit.
