More generally, I've noticed I tend to underestimate how much time it passes when I'm directly controlling how fast I'm going (climbing stairs, driving on an open road, reading) and overestimate it when I'm not (using an elevator, driving in congested traffic, watching a video).

Short-distance public transport is an exception: once I'm on the bus, it feels like it takes 5 minutes to get from home to the university, but it actually takes 20.
