"suitcase on wheels" thingies.

These things could become quite a hazard. Even in non-threatening
situations, like hurrying for a train, I'll judge my quickest route
across the station concourse (particularly Victoria) by scanning the
general movement of people's heads. If I see a gap, I'll make a
beeline for it. However, you don't see the slow moving
suitcase-on-wheels until you're practically falling over it.

If you're moving so fast that you're in danger of "falling over" a large
suitcase that you've failed to notice, it sounds as if your speed
through a crowded concourse is itself a hazard. Don't complain about
other people if you can't be bothered to adjust your speed to the
conditions.
