I was watching through the Marvel movies just to catch up. Mostly I was surfing on my phone at the same time, as they're not that engaging. At one point during Winter Soldier though I caught myself having put down the phone and was sitting on the edge of my sofa, fully engaged in the action scene with an elevated heart rate.

Some time later I saw the "Stuntmen React" where they went through the scene, and it suddenly all made sense: that whole scene, the chase/fight on the overpass, was almost entirely practical stunts.
