I never found them scary, but I suppose it depends what you're used to. In some other countries I find escalators to be annoyingly slooooow.

Angel Station's escalator can be done in seven seconds — if you have skis: https://youtu.be/fFqQOlYE4EE?t=25

(I used to use it regularly late at night, when the up escalator was usually empty. Sprinting up, two steps at a time, is quite satisfying.)
