Also remember, commercial aircraft often won’t try and stop as quick as possible. They’re usually given a taxiway to exit the runway off, so there’s no need to try and slow down as hard as possible, then taxi at 25 knots for half the runway etc. most commercial airports have the high speed runway exits in specific positions along the runways. The aircraft can just brake at say 50% and use spoilers, continue their roll and exit at speed off the runway. It’s quicker and more efficient.
ATC will try to give a taxiway exit near their terminal / gate, or to assist with traffic flow.
In short, yes the aircraft can stop as fast as they do in IF, but in real life pilots aren’t using full reverse and full maximum brakes a long with spoilers on long runways that can handle A380 departures etc! That just causes major wear on both for no reason and just increases runway occupancy time.
Also IF only gives us the one autobrake setting - maximum! Real commercial aircraft have an autobrake with usually around 3 setting for landings, 1, 2 and maximum. We don’t have that luxury.
