Serious Talk of a Monorail Line in Florida

There is a historic problem with monorails that has never been solved. Monorails above 30 - 35 MPH are dynamically unstable. That is they will shake them selves apart at those speeds. That is why Disney limits theirs to 25 MPH. Research has shown that active controls can dampen the unstable but what happens if it fails at high speed ? To get an idea of the cost the F-16 has active controls that almost double the cost of the aircraft.

Sao Paulo in Brazil has two monorail lines as part of it's rapid transit network. Below is a video shot from the head-end of a monorail train on line 15 -

I'm guessing 30 to 40 mph
