It is sloped so water will drain away from the buildings. Most all loading docks are designed this way to prevent the depot buildings from being flooded. There are these things called breaks in both strollers and wheelchairs.
"Breaks" in a stroller can be induced in many ways, including being hit by a train.
"Brakes" will prevent a stroller from rolling away..... ;-)
Hey, no need to get snarky. I just said I wondered why the surface wasn’t flat. I can wonder, can’t I? You gave an acceptable explanation.
That said, I stand by my observation that most people will assume the surface is flat and not slightly slopped. Ergo, they may not see a reason to put the brake on.
Note again that I said nothing about the mother needing to sue.
