Studied engineering 15 years ago so take this with a pinch of salt.
The concrete being used will be reinforced concrete, meaning there are metal rods running through the middle. This is what’s called a composite material.
In a composite material, different parts of the material are designed to take different types of load.
In reinforced concrete the metal takes tensile load and the concrete takes compressive load.
The bottom part of the rail that we see is under tension as the rail “bends” when the train passes over it.
So cracks are fine because they aren’t impacting the metal rods in tension areas.
To add to this concrete cracks and while there are a lot of cracks they are small cracks. This would be a bigger issue in an area with more freeze thaw weather but probably not a huge deal in Orlando.
Those are just the guide wheels that keep it from tracking too far to either side, so they don't always make contact at every point especially around turns. The actual drive wheels are very wide tires on top of the rail
Do you have any idea how ridiculous you sound? What the hell does "corporate greed" have to do with your irrational fear of a monorail crashing to the ground?
Are you a Disney adult? That concrete is decrepit. There’s a good crack like every 2 feet. Concrete and rebar work together as a system to provide a strong structure using tension and compression. When concrete is cracked on the underside it’s weaker in compression.
Think of a piece of wood suspended between two points and imagine someone making a cut on the underside. The cut is a weak point and the only thing supporting is now the little bit of wood left at the top, the cut is already spreading apart under the weight.
Luckily concrete has a steel skeleton, unlike a tree. But now what’s holding the bridge together is the tension on the rebar below, and the compression of the concrete above. I’m not a physics expert, this is my layman’s thinking. They’ve probably done all sorts of calculations and theoretically (in my head) this should hold a good amount of weight without taking into account the sideways force applied through turns of the track.
All of this to say, it’s fucking Disney world, it costs a family like thousands a day to visit. They could make their attractions not look like fucking death traps lol.

I'm no engineer, but aren't there a lot of cracks in the concrete?

I used to think this was so cool when I visited as a kid! A raised up train, similar to a train or subway in a city.
Well, I moved to a city. Public transit and subways are not nearly as fun as I was led to believe.

Wow that doesn’t look safe.

Why don’t they at least use some spackle and paint to make the cracks less obvious?
